If you're running a biogas upgrading plant or landfill gas treatment system, there's a good chance your carbon spec says "Jacobi" somewhere on it. The AddSorb and EcoSorb series have become default specifications for biogas purification across European and North American markets — covering everything from bulk H₂S removal to siloxane polishing.
That position is based on real performance. Jacobi's biogas carbons are engineered for the specific contaminant mix in biogas streams — hydrogen sulfide, ammonia, siloxanes, and VOCs that damage CHP engines and contaminate upgraded biomethane.
But "engineered for biogas" also means "priced through a distributor network." If you're consuming 20–100+ tons of carbon per year, the question worth asking is: does an equivalent carbon exist at factory-direct pricing — and does it actually perform the same?
This article breaks down Jacobi's current biogas product line, what each grade actually does, and how Huamei's HME-AC™ pellet carbon and custom-impregnated carbons compare on the parameters that determine whether your biogas meets pipeline or engine specifications.
Jacobi organizes its biogas carbons into three product families, each targeting different contaminants. Here's the current lineup:
| Jacobi Grade | Primary Target | Mechanism | Key Feature |
|---|---|---|---|
| AddSorb VA6-BG | H₂S | Catalytic oxidation
(impregnated) |
Standard biogas
H₂S grade |
| AddSorb VA12-BG | H₂S

| AddSorb OX20 | H₂S | Catalytic oxidation | Non-impregnated,

| AddSorb OX30 | H₂S | Catalytic oxidation | Higher capacity

| AddSorb VA10 | H₂S, mercaptans | Chemical + physical

| Jacobi Grade | Primary Target | Mechanism | Key Feature |

| AddSorb VB1-BG | NH₃, amines | Acid-impregnated

| Jacobi Grade | Primary Target | Mechanism | Key Feature |
|---|---|---|---|
| EcoSorb BS | Siloxanes (D4, D5, L2) | Physical adsorption | Optimized pore structure
for siloxane molecules |
| EcoSorb GXC | Siloxanes + VOCs | Physical adsorption | Broader spectrum,
multi-contaminant |
| ReSorb VT | VOCs + trace siloxanes | Physical adsorption | Regenerable grade
for thermal swing systems |
The key insight: Jacobi doesn't use one carbon for everything. They split the job into specialized grades — impregnated carbons for reactive gases (H₂S, NH₃), virgin carbons for physical adsorption tasks (siloxanes, VOCs), and regenerable grades for systems with thermal swing capability. Your replacement strategy needs to respect these distinctions.
Biogas purification isn't generic adsorption. The contaminant mix — H₂S, NH₃, siloxanes (D4, D5, L2), mercaptans, and halogenated compounds — demands specific carbon properties for each target:
H₂S removal operates through catalytic oxidation on the carbon surface. The carbon needs:
NH₃ removal requires the opposite chemistry — acid-impregnated carbon (typically phosphoric acid) that reacts with alkaline gases. Standard alkaline carbon does almost nothing for NH₃. This is why Jacobi has a separate grade (VB1-BG) rather than using their H₂S carbons for both.
Siloxane removal is primarily physical adsorption driven by:
The engineering reality: A single carbon grade cannot handle all three targets effectively. Most biogas plants run multi-stage systems with different carbons matched to each contaminant — and that's exactly what you should plan for when evaluating alternatives.
Replacing Jacobi biogas carbons isn't one product swap — it's matching the right Huamei grade to each Jacobi grade's function. Here's the mapping based on contaminant target and mechanism:
| Parametre | Jacobi AddSorb H₂S Grades (typical) | Huamei KOH-Impregnated Pellet | Huamei HME-AC™60 (Virgin) |
|---|---|---|---|
| Form | Extruded pellet | Extruded pellet | Extruded pellet |
| Çap | 4mm | 3mm or 4mm | 4mm |
| Mechanism | Impregnated (VA6/VA12) or catalytic (OX series) | KOH-impregnated (chemical + physical) | Catalytic oxidation (physical only) |
| H₂S capacity | Published per grade | 5–8× higher | Standard catalytic capacity |
| CTC | 50–60% (typical) | Varies with impregnant loading | 60% |
Replacement logic:
| Parametre | Jacobi AddSorb VB1-BG | Huamei H₃PO₄-Impregnated Pellet |
|---|---|---|
| Raw material | Coal-based | Coal-based (Ningxia anthracite) |
| Form | Extruded pellet | Extruded pellet |
| Çap | 4mm | 3mm or 4mm |
| Mechanism | Acid-impregnated (reacts with NH₃) | Phosphoric acid-impregnated (reacts with NH₃) |
| Target | NH₃, amines | NH₃, amines |
Replacement logic: NH₃ removal requires acid-impregnated carbon — the chemistry is the opposite of H₂S removal. Do NOT use KOH-impregnated or standard alkaline carbon for NH₃; it won't work. Huamei produces phosphoric acid (H₃PO₄) impregnated pellet carbon specifically for alkaline gas treatment, which is the direct equivalent of VB1-BG.
| Parametre | Jacobi EcoSorb/ReSorb (typical) | Huamei HME-AC™70 | Huamei HME-AC™80 |
|---|---|---|---|
| Raw material | Coal-based / coconut shell | Coal-based (anthracite) | Coal-based (anthracite) |
| Form | Pellet or granular | Extruded pellet | Extruded pellet |
| Çap | 4mm | 4mm | 4mm |
| Mechanism | Physical adsorption | Physical adsorption | Physical adsorption |
Replacement logic:
| Jacobi Grade | Target Contaminant | Huamei Equivalent | Key Matching Criteria |
|---|---|---|---|
| AddSorb VA6-BG | H₂S | KOH-impregnated pellet (custom) | Match impregnant
type + loading % |
| AddSorb VA12-BG | H₂S (high conc.) | KOH-impregnated pellet (high loading) | Higher KOH loading

| AddSorb OX20 | H₂S | HME-AC™60 | Virgin, alkaline pH,

| AddSorb VA10 | H₂S + mercaptans | KI-impregnated pellet (custom) | Discuss mercaptan

| EcoSorb BS | Siloxanes | HME-AC™70 | CTC 70%, pore

| EcoSorb GXC | Siloxanes + VOCs | HME-AC™80 | CTC 80%, broad-spectrum adsorption |
| ReSorb VT | VOCs (regenerable) | HME-AC™70 / HME-AC™80 | Confirm regen
temperature compatibility |
| Factor | Jacobi AddSorb / EcoSorb | Huamei HME-AC™ / Impregnated |
|---|---|---|
| Pricing model | Distributor network | Factory-direct |
| Distribution layers | Manufacturer → Distributor → End user | Manufacturer → End user |
| MOQ (virgin pellet) | Varies (typically 5–10 tons via distributor) | 3 tons |
| Örnek | Through distributor | Free sample direct |
| COA | Yes | Yes (SGS available on request) |
| Custom impregnation | Limited to catalog grades | KOH, NaOH, H₃PO₄, KI — adjustable loading % |
The structural price difference is distribution economics: Jacobi passes through intermediaries between factory and end user; Huamei ships direct. For a biogas plant consuming 40–100 tons/year across multiple grades, the annual cost difference funds comprehensive pilot testing in Year 1 — and delivers ongoing savings every year after.
This deserves its own section because it's the most common mistake when switching biogas carbon suppliers.
You cannot replace impregnated carbon with virgin carbon. If your current Jacobi grade is AddSorb VA6-BG (KOH-impregnated for H₂S) or VB1-BG (acid-impregnated for NH₃), replacing it with a standard HME-AC™60 pellet will fail — the virgin carbon lacks the chemical reactivity needed for high-efficiency removal of reactive gases.
Conversely:
When requesting quotes from Huamei, always specify:
Huamei produces both KOH and H₃PO₄ impregnated carbons with adjustable loading — but they need your specific requirements to match the product correctly.
Jacobi offers several H₂S grades for biogas: AddSorb VA6-BG and VA12-BG (impregnated, high sulfur capacity), AddSorb OX20 and OX30 (non-impregnated catalytic), and AddSorb VA10 (H₂S plus mercaptans). The choice depends on H₂S inlet concentration, whether you need impregnated or catalytic removal, and bed design. For direct factory-sourced equivalents, Huamei's HME-AC™ pellet carbon (virgin catalytic) and custom KOH-impregnated pellets match these specifications.
Yes — if you match the mechanism, not just the format. For H₂S grades: impregnated Jacobi carbons (VA6-BG, VA12-BG) must be replaced with impregnated equivalents. For siloxane grades (EcoSorb BS, GXC): match CTC value and pore structure with high-CTC virgin pellet carbon like HME-AC™70 or HME-AC™80. Always run a pilot breakthrough test before committing to a full bed replacement.
AddSorb grades target reactive gases — H₂S (VA6-BG, VA12-BG, OX20, OX30, VA10) and NH₃ (VB1-BG) — using catalytic or chemical impregnation mechanisms. EcoSorb grades (BS, GXC) target siloxanes and VOCs using physical adsorption — they rely on pore structure rather than chemical treatment. ReSorb VT is the regenerable variant for thermal swing systems. They're different product families for different contaminant targets.
Typical consumption ranges from 10–100+ tons/year depending on plant capacity, contaminant levels, and number of treatment stages. A 500 Nm³/hr biogas upgrading plant with 2,000 ppm H₂S inlet typically consumes 20–40 tons/year of H₂S-grade carbon. Siloxane polishing stages consume less (5–15 tons/year) but require more frequent replacement due to faster saturation.
Yes. Huamei produces custom-impregnated pellet activated carbon including KOH-impregnated (for H₂S/acid gases), NaOH-impregnated, H₃PO₄-impregnated (for NH₃/alkaline gases), and KI-impregnated (for mercaptans). Impregnant loading percentage is adjustable to match your target contaminant concentration. MOQ is 10 tons per impregnation type, with 28-day lead time including impregnation, curing, and QC.
Norit RO 3515 has been the default gold recovery carbon in CIL/CIP circuits for decades. If you've worked in gold mining in South Africa, West Africa, or Australia, chances are RO 3515 was the first carbon your plant loaded — and possibly the only one your metallurgist ever approved.
That market position was earned. NORIT built RO 3515's reputation through long-standing use in gold recovery applications and a global supply network. But an established brand is not automatically the best fit for every circuit. Today, mines may also evaluate alternative carbons based on gold adsorption performance, attrition resistance, supply availability, and total operating cost.
This article compares RO 3515 against HMGOLD™7500 from Huamei Carbon — spec by spec, using Norit's published product data and Huamei's SGS test results (Report No. MSRCZ2500346-01A). Where the numbers speak, we let them. Where they don't, we say what's missing.

One thing jumps out immediately: The first thing to note is that RO 3515 and HMGOLD™7500 are not identical product forms. RO 3515 is an extruded activated carbon, while HMGOLD™7500 is a coconut-shell granular carbon. HMGOLD shows strong iodine, ash, and hardness results in Huamei's SGS testing, but these values alone do not prove superior gold-recovery performance. Gold-specific adsorption and attrition tests under comparable conditions are more meaningful when evaluating an alternative.Iodine is 100+ mg/g higher. Ash is half. The real question is whether those spec-sheet advantages translate to performance advantages in your specific circuit — and that requires testing, not assumptions.
Understanding why mines use RO 3515 helps you evaluate whether switching makes sense:
Track record: RO 3515 has a long history of use in gold recovery and is widely recognized in CIL/CIP applications. Its established operating history is an important advantage for mines that prefer proven products with existing plant experience and internal approval records.
Consistency: Norit's manufacturing process delivered batch-to-batch consistency that mines relied on. When you ordered RO 3515, you got RO 3515 — the carbon performed within predictable bounds every time.
Distribution reach: From Johannesburg to Perth to Accra, Norit distributors could deliver. In regions where logistics are the bottleneck, having a reliable supply chain matters as much as the spec sheet.
Inertia: This is the honest one. Many mines run RO 3515 because they've always run RO 3515. The metallurgist who approved it may have retired. The procurement team reorders on autopilot. Nobody has run a comparative trial in years — because why would you change something that works?
That last point is the opening for HMGOLD. "Works" and "optimal" are different things. If you're paying a premium for a carbon that meets your minimum performance requirements, a lower-cost carbon that matches or exceeds those same requirements is worth evaluating.
Iodine number isn't the primary metric for gold recovery carbon — K value matters more. But a higher iodine number indicates greater total micropore volume, which correlates with overall adsorption capacity. At 1208 mg/g (SGS verified), HMGOLD™7500 has roughly 15% more adsorptive capacity than RO 3515's minimum specification.
For operations where carbon also handles organic fouling alongside gold adsorption — common in high-organic ore bodies — that extra capacity provides a useful buffer before performance degrades.
This is the biggest measurable gap. HMGOLD's ash is roughly half of RO 3515's maximum specification.
Why this matters in your circuit:
Elution efficiency: Inorganic ash residues trap gold within the carbon structure during Zadra or AARL stripping. Lower ash = cleaner stripping = less residual gold left on carbon after each elution cycle. Over hundreds of cycles, that gold retention compounds into real losses.
Reactivation longevity: Ash doesn't burn off during thermal reactivation. It accumulates cycle after cycle. Carbon starting at 2.52% ash builds up contamination slower than carbon starting at 5%, maintaining its gold loading capacity through more reactivation cycles before requiring replacement.
Doré purity: Lower-ash carbon contributes fewer inorganic impurities to your final gold precipitate. If your refinery penalizes you for impurities in doré bars, your carbon's ash content directly affects your refining charges.
Here's where things get interesting. Norit/Cabot does not typically publish K value and R value for RO 3515 in the same format that Jacobi publishes for PICAGOLD G210AS.
HMGOLD™7500 publishes both:
These are competitive numbers. For context, Jacobi G210AS — another premium gold carbon — publishes K=28 kg/t and R=60%. HMGOLD™7500's K value matches G210AS exactly; the R value is 2 percentage points lower, which is within normal batch variation for most CIL circuits.
The fact that HMGOLD publishes K and R values while Norit does not is itself significant. If you're currently running RO 3515, you probably don't know its K and R values — unless you've tested it yourself. That means you're paying premium pricing for a carbon whose gold-specific performance metrics you may have never quantified.
RO 3515 comes in one size. HMGOLD offers three — which matters because mesh size selection directly affects circuit performance:
If you're running a CIP circuit on 6×12 carbon because that's all your supplier offers, you may be leaving performance on the table.
No amount of spec-sheet comparison replaces 40+ years of operational data. RO 3515 has been tested, approved, and documented in more CIL/CIP plant operating manuals than any other gold carbon. When your client requires a "proven carbon with established track record," RO 3515 checks that box without discussion.
HMGOLD™7500 is growing — Tanzania, Ghana, South Africa, Egypt, Azerbaijan — but it doesn't have decades of data yet.
Some mining companies have approved vendor lists. RO 3515 is on most of them. Getting HMGOLD approved requires a formal evaluation process — lab testing, plant trial, metallurgical report, management sign-off. That process takes 3–6 months and costs money.
If your company's procurement policy mandates approved-vendor-only purchasing, you'll need to run that approval process before HMGOLD becomes an option — regardless of how good the specs look.
Cabot's distributor network provides local technical support in major mining regions. If you have a carbon performance issue, your Cabot rep can visit your site. Huamei's support is primarily remote (WhatsApp, email, video calls) with periodic site visits for key accounts.
For operations in remote locations where on-site technical support matters, this is a real consideration — not a deal-breaker, but a factor.
| Factor | Norit RO 3515 | Huamei HMGOLD™7500 |
|---|---|---|
| Pricing model | Cabot distributor network | Factory-direct |
| Distribution layers | Manufacturer → Regional distributor → Local agent → Mine | Manufacturer → Mine |
| MOQ | Varies by distributor (typically 20+ tons) | 10 tons |
| Lead time | 2–6 weeks (dependent on distributor stock) | 2–3 weeks production + shipping |
| Örnek | Through distributor | Free 1–2 kg sample direct |
| COA | Yes | Yes (SGS reports available) |
The structural price difference is distribution economics. RO 3515 passes through 2–3 intermediaries between Cabot's factory and your mine. Each adds margin. HMGOLD ships factory-direct from Fujian, China — one invoice, no intermediary markup.
On equivalent specifications, the price gap is significant. But "significant" varies by region, volume, and current market conditions. Get current quotes from both suppliers for your specific requirements before making assumptions based on list prices.

| Pricing | Distributor markup | Factory-direct | HMGOLD |

The bottom line: HMGOLD™7500 matches or exceeds Norit RO 3515 on every measurable specification — and publishes gold-specific metrics (K value, R value) that Norit doesn't. What HMGOLD lacks is the decades of operational track record and automatic brand-approval status that RO 3515 carries. If your procurement decision is based on specs and price, HMGOLD wins. If it's based on institutional history and approved-vendor lists, Norit wins. For most operations, the smart move is to run a parallel trial and let the data decide.
HMGOLD™7500 from Huamei Karbon matches or exceeds RO 3515 on published specifications: higher iodine (1150 vs ≥1050 mg/g), lower ash (2.52% vs ≤5%), and comparable hardness. Both are coconut shell, steam-activated carbons designed for CIL/CIP gold recovery. A bottle-roll test and plant trial with your specific ore is recommended to confirm equivalent performance in your circuit.
Yes. Norit RO 3515 is now manufactured by Cabot Corporation, which acquired Norit in 2012. The product continues to be available through Cabot's global distributor network. Some industry professionals report longer lead times and availability fluctuations since the acquisition, but the product specification remains unchanged.
Norit RO 3515 specifies a minimum iodine number of ≥1050 mg/g. This measures total micropore volume using the ASTM D4607 method. While useful as a general quality indicator, iodine number is not the primary metric for evaluating gold recovery carbon performance — K value (gold loading capacity) and R value (adsorption kinetics) are more relevant for CIL/CIP applications.
Three main drivers: (1) pricing — RO 3515 routes through Cabot's multi-layer distributor network, adding margin at each step; (2) alternatives have improved — Chinese manufacturers like Huamei now offer SGS-verified carbons with equivalent or superior specifications; (3) data transparency — newer brands publish gold-specific metrics (K value, R value) that help metallurgists make informed comparisons, while Norit relies on legacy reputation.
Exact pricing varies by volume, destination, and current market conditions. The structural difference comes from distribution: RO 3515 passes through 2–3 intermediaries (Cabot → regional distributor → local agent), while HMGOLD ships factory-direct. Request current quotes from both suppliers for your specific requirements — pricing from even 6 months ago may not reflect today's market.
Most activated carbon comparisons stop at the spec sheet — iodine number, hardness, ash content. Useful for procurement paperwork, but not for predicting what happens inside a CIL circuit where carbon spends months being pumped through abrasive ore slurry, screened at high velocity, stripped in acid, and thermally reactivated — over and over.
This article compares Jacobi PICAGOLD G210AS and Huamei HMGOLD™7500 based on verified data: Jacobi's official gold recovery brochure parameters for G210AS, and Huamei's SGS test report (No. MSRCZ2500346-01A) for HMGOLD™7500. Where data is available, we compare directly. Where it isn't, we say so.

*Jacobi's gold recovery brochure does not use iodine number as a primary specification for G210AS. This is standard practice — iodine measures total microporosity, not gold-specific adsorption capacity. K value and R value are the metrics Jacobi uses to define gold carbon performance.
Carbon attrition is the single largest source of unrecoverable gold loss in CIL circuits. When carbon breaks into fines smaller than your screen aperture, those fines — loaded with adsorbed gold — pass through inter-stage screens and exit with tailings.
These numbers come from different test methods using different equipment, sample preparation, and measurement criteria. A direct percentage-to-percentage comparison is not valid. Both values indicate high-strength carbons, but you cannot conclude that one is harder than the other based on these numbers alone.
Jacobi provides three attrition-relevant metrics (ball-pan hardness, rolling bottle attrition, platelet content) that together give a comprehensive picture of G210AS durability in CIL circuits.
Huamei provides one metric (GB/T strength) from a different test standard.
If attrition-related gold loss is a primary concern for your operation — and for most CIL plants, it should be — this data gap matters. Request rolling bottle attrition and platelet testing from Huamei before making a procurement decision based on durability.
This is one area where HMGOLD has a clear, verifiable edge. Lower ash = fewer inorganic mineral residues = cleaner carbon matrix.
Why this matters in CIL:
Elution efficiency: During Zadra or AARL stripping, inorganic residues can trap gold within the carbon structure, reducing strip recovery per cycle. Lower ash content means cleaner stripping and less residual gold left on carbon after elution.
Reactivation quality: During thermal reactivation, mineral ash doesn't burn off — it accumulates cycle over cycle. Carbon that starts with 2.52% ash accumulates less than carbon starting at 4%, meaning the low-ash carbon maintains its performance characteristics over more reactivation cycles.
Contamination risk: In operations producing doré bars or shipping gold precipitate for refining, lower-ash carbon contributes fewer impurities to the final product.
Both G210AS and HMGOLD™7500 are coconut shell, steam-activated carbons. Both are coconut-shell, steam-activated carbons, but their actual elution performance should be verified under identical operating conditions.
Ash content (advantage: HMGOLD): As discussed above, HMGOLD's lower ash (2.52% vs ≤4%) theoretically supports cleaner stripping with less gold retention per cycle.
Pore size distribution: Two carbons with different iodine numbers may have different mesopore-to-micropore ratios. Gold cyanide complexes (~0.6nm) load preferentially in mesopores. Carbons with more micropores may trap gold more tightly, making it harder to strip. Without comparative mercury porosimetry data for both products, this remains a theoretical consideration.
What to test during your trial: Track gold-on-carbon before and after each elution cycle for both carbons. If one consistently retains more gold after stripping, that's a quantifiable cost — both in gold recovery and in progressive performance degradation.
| Factor | Jacobi PICAGOLD G210AS | Huamei HMGOLD™7500 |
|---|---|---|
| Pricing model | Distributor/agent network | Factory-direct |
| Sample availability | Through distributor | Free 1–2 kg sample direct |
| COA with shipment | Yes | Yes (SGS reports available) |
The structural price difference comes from distribution model: Jacobi sells through a global agent network (each adding margin), while Huamei ships factory-direct. On equivalent specifications, factory-direct pricing is typically significantly lower per ton.
For exact pricing: request quotes from both suppliers for your specific volume, destination, and delivery schedule. Published price ranges become outdated quickly — get current numbers.
| Category | Jacobi G210AS | HMGOLD™7500 |
|---|---|---|
| Gold loading data (K value) | 28 kg/t (published) | 28 kg/t |
| Adsorption kinetics (R value) | 60% (published) | 58% |
| Attrition data | <1.0% rolling bottle, <4% platelets | ＜2% |

| MOQ flexibility | 20 tons | 10 tons |
| Track record in CIL | Decades, global | Growing, primarily Africa/Asia |
The bottom line: Jacobi wins on data transparency — they publish the gold-specific metrics (K, R, attrition, platelets) that matter most for CIL procurement decisions. HMGOLD wins on ash content and pricing structure, but has significant data gaps on the metrics that CIL metallurgists need to see before approving a carbon switch.
G210AS has more comprehensive published performance data — K value (28 kg/t), R value (60%), rolling bottle attrition (<1.0%), and platelet content (<4%). HMGOLD™7500 has verified advantages in ash content (2.52% vs ≤4%) and offers factory-direct pricing with lower MOQ.
According to Jacobi's official gold recovery brochure, the typical K value (gold loading) for G210AS is 28 kg/tonne, measured by the Mintek method. K value indicates how much gold the carbon loads from cyanide solution under standardized conditions. This is a competitive value for premium gold recovery carbon.
HMGOLD7500 can be evaluated as an alternative, but equivalence should be confirmed through K/R, attrition and plant-trial data.
Distribution structure. Jacobi sells through a global network of agents and distributors who each add margin. HMGOLD ships factory-direct from Huamei Karbon in China with no intermediary markup. Both use coconut shell raw material and steam activation. The price difference reflects distribution economics, not necessarily a difference in manufacturing quality.
Possibly — but you must verify through testing, not assumptions. HMGOLD's published specifications (iodine 1150 mg/g, ash 2.52%, 6×12 mesh) indicate a high-quality coconut shell carbon suitable for CIL. Run a parallel plant trial in one CIL train for 8–12 weeks, tracking gold recovery, attrition, and elution performance against your current G210AS results before committing to a full switch.

Haycarb's strength is consistency. When you order RCGC, you're getting a product backed by 50+ years of process control in coconut shell activation. Their quality management system is mature, and their brand carries weight with mining engineers who've used it across multiple projects.
That said, you're also paying for that brand. And as China-based manufacturers have closed the quality gap in the last decade, the value equation has shifted.
RCGC is Haycarb's gold recovery grade — designed specifically for carbon-in-leach (CIL), carbon-in-pulp (CIP), and carbon-in-column (CIC) applications. Here's what a typical RCGC Technical Data Sheet looks like:
| Parametre | RCGC Typical Spec | Test Method |
|---|---|---|
| Raw material | Coconut shell | — |
| Activation | Steam activated | — |
| ağ boyutu | 6×12 (1.70–3.35 mm) | ASTM D2862 |
| İyot sayısı | ≥1050 mg/g | ASTM D4607 |
| Hardness (ball-pan) | ≥97% | ASTM D3802 |
| Nem | ≤5% | ASTM D2867 |
| kül içeriği | ≤3% | ASTM D2866 |
| Bulk density | 0.48–0.54 g/cm³ | ASTM D2854 |
| Surface area (BET) | ≥1000 m²/g | BET method |
| Gold adsorption rate (K value) | Published on request | Mintek method |
These are solid specifications. The 97% hardness floor is what makes RCGC survive the abrasion of CIL circuits — where carbon is constantly pumped, screened, and recycled through aggressive pulp environments. The iodine number at 1050+ ensures adequate gold loading capacity.
To be fair to Haycarb — there are legitimate reasons RCGC became an industry standard:
1. Track record in African gold mines. Haycarb has supplied major operations in Ghana, Tanzania, Mali, Burkina Faso, and South Africa for decades. When a mine's metallurgical team has 10+ years of plant data on RCGC, switching carries perceived risk.
2. ESG documentation. Haycarb's green charcoal program and Colombo Stock Exchange listing mean they can provide ESG compliance documentation that some publicly-traded mining companies require from suppliers.
3. Consistent quality batch-to-batch. Their vertically integrated model — controlling charcoal production through to activation — reduces variability. You generally get what the TDS says.
4. Global distribution. Warehouses in multiple countries mean shorter lead times for urgent orders, even if the per-ton cost is higher.
1. Premium pricing. RCGC typically lands 30–50% above factory-direct alternatives from Chinese manufacturers producing equivalent specs. For a mine consuming 200+ tons/year, that's a significant cost difference.
2. Lead times during peak demand. Despite their capacity, Haycarb's order book fills up — especially when gold prices spike and every mine is restocking. Lead times of 6–8 weeks are not uncommon during peak periods. Factory-direct suppliers in China often ship within 2–3 weeks.
3. Limited customization. RCGC is a standard product. If your circuit needs a slightly different mesh distribution, higher iodine value, or acid-washed variant, Haycarb can accommodate but at premium pricing and longer lead times. Smaller manufacturers are generally more flexible.
4. Minimum order quantity. Haycarb's MOQ is typically 20+ tons. For small-scale operations or trial orders, this can be a barrier. Factory-direct Chinese manufacturers commonly accept 10-ton trial orders.
Here's where the comparison gets concrete. We'll use published specifications from Haycarb and two factory-direct manufacturers.
| Parametre | Haycarb RCGC | HMGOLD™ 7500 (Huamei) |
| Raw material | Coconut shell (Sri Lanka) | Coconut shell (Philippines) |
| ağ boyutu | 6×12 | 6×12 |
| İyot sayısı | ≥1050 mg/g | ≥1100 mg/g |
| Sertlik | ≥99% | ≥99% |
| kül içeriği | ≤3% | ≤3% |
| Nem | ≤5% | ≤5% |
| Bulk density | 0.48–0.54 g/cm³ | 0.48–0.52 g/cm³ |
| Surface area | ≥1000 m²/g | ≥1050 m²/g |
| CTC | Not typically published | ≥60% |
| MOQ | 20 tons | 10 tons |
| Lead time | 2–3 weeks | 2–3 weeks |
| Pricing model | Distributor/agent network | Factory-direct |
The numbers tell the story: on paper, the factory-direct alternatives match or exceed RCGC on key parameters (iodine, hardness, ash). The HMGOLD™ 7500, for example, specs at ≥1100 iodine and ≥99% hardness — both above RCGC's guaranteed minimums.
But paper specs aren't the whole picture.
Experienced metallurgists know that two carbons with identical TDS numbers can perform differently in the same circuit. Here's what to evaluate beyond the data sheet:
Gold loading capacity (K value and R value)
The K value measures how fast carbon adsorbs gold from solution. The R value measures how much gold the carbon can hold. These are the metrics that actually predict CIL/CIP performance — not iodine number.
Haycarb publishes K and R values on request. If you're comparing alternatives, demand these numbers from every supplier. Any manufacturer serious about gold recovery carbon will have Mintek or equivalent test data available.
Attrition resistance under real conditions
Ball-pan hardness (ASTM D3802) is a standardized test, but it doesn't perfectly replicate the specific abrasion conditions in your circuit. Carbon that tests at 99% hardness in a lab may lose 2% vs 1.5% per cycle in a high-screen-velocity CIL plant. The only way to verify: run a trial.
Elution behavior
How cleanly does the gold strip during elution? Some carbons hold gold more tightly than others, requiring higher temperatures or longer strip times. This affects your overall gold recovery and operating costs. Request elution test data or, better, run your own strip test on a sample batch.
Fines generation
Even high-hardness carbon generates fines over time. The question is how much and how fast. Excessive fines mean gold losses (fines pass through screens), increased thickener load, and higher replacement costs. Track fines percentage per cycle during your trial.
Let's model the actual cost impact. Assume a mid-size CIL operation consuming 150 tons of carbon per year:
| Cost factor | Haycarb RCGC | Factory-direct (China) |
|---|---|---|
| FOB price (estimated range) | $3,500–5,200/ton | $3,200–3,800/ton |
| Shipping (to West Africa) | Similar (both export via container) | Similar |
| Annual carbon cost (150 tons) | $525,000–780,000 | $480,000–570,000 |
| Potential annual savings | — | $45,000–210,000 |
| Sample/trial cost | Usually available, MOQ 20T | 1–2 kg free sample, MOQ 10T |
A $100,000–150,000 annual saving is worth investigating — even if it requires a 3-month parallel trial to validate performance.
Important caveat: These are estimated ranges based on market conditions. Actual pricing depends on volume, payment terms, and current supply/demand. Request quotes from both sides to get real numbers.
If you're currently on RCGC and considering a switch, here's a low-risk evaluation process:
Contact the alternative supplier and ask for:
Any manufacturer that can't provide these documents isn't ready for gold mining supply.
Run your own lab tests. Compare iodine number (ASTM D4607), ball-pan hardness (ASTM D3802), and ash content (ASTM D2866) against your current RCGC batch results. Not against Haycarb's published minimums — against what you're actually receiving.
Load the alternative carbon into one circuit or one adsorption stage while running RCGC in the others. Track:
Run for a minimum of 8–12 weeks to capture performance over multiple adsorption/elution cycles.
Don't just compare purchase price. Factor in:
If the alternative matches RCGC on performance and saves $100+/ton, you have your answer.
Based on published case studies and export records, the shift from premium-brand carbon to factory-direct alternatives has been most pronounced in:
West African gold mines (Ghana, Burkina Faso, Mali): These markets were early Haycarb strongholds but have increasingly adopted Chinese-manufactured carbon as quality has proven equivalent in-plant. A 56-ton HMGOLD™ shipment to a Ghana CIP operation showed the mine upgraded from 6×16 to 6×12 mesh during the switch — improving both carbon retention and gold loading.
East African operations (Tanzania, Ethiopia): Chinese manufacturers have built strong export records here, particularly for CIL circuits.
South American mines: Peru, Brazil, and Colombia have seen increasing adoption of factory-direct coconut shell carbon, driven by cost pressure and improved logistics from Chinese ports.
Australian mines remain more brand-loyal, partly due to established supply agreements and proximity to Southeast Asian production.
RCGC is one of the most proven gold recovery carbons on the market, backed by decades of plant data. "Best" depends on what you're optimizing for — if brand reputation and ESG documentation are priorities, RCGC delivers. If you're optimizing for cost-per-gram-of-gold-recovered and are willing to trial alternatives, factory-direct options with equivalent specs may deliver equal performance at 30–50% lower cost. The only way to determine what's "best" for your specific circuit is a parallel plant trial.
Both are coconut shell, steam-activated, 6×12 mesh gold recovery carbons. The key differences: RCGC uses Sri Lankan coconut shells and is produced in Haycarb's own facilities; HMGOLD™ uses Indonesian/Philippine shells and is manufactured in China. On specifications, HMGOLD™ 7500 guarantees ≥1100 iodine and ≥99% hardness vs RCGC's ≥1050 iodine and ≥97% hardness. Pricing differs significantly — HMGOLD™ is factory-direct while RCGC goes through distributor networks. Performance in-plant should be validated through trial.
Haycarb doesn't publish pricing — it varies by volume, destination, and distributor. Market estimates for RCGC typically range $2,200–2,800/ton FOB, depending on order size and delivery terms. Factory-direct alternatives from Chinese manufacturers typically range $1,400–1,800/ton FOB for equivalent specifications. Request quotes from both sides for your specific volume and destination.
Yes — if the alternative meets or exceeds the critical performance parameters (K value, R value, hardness, and attrition rate) in your specific circuit. The key is testing, not assuming. Run a parallel plant trial with 10–20 tons over 8–12 weeks. If gold recovery rates match within your acceptable tolerance, the cheaper carbon delivers the same metallurgical outcome at lower cost.
Haycarb ships from Sri Lanka (primary), Thailand, and Indonesia. They have warehouse/distribution points in several countries for faster delivery. Lead times from Sri Lanka to West Africa are typically 4–8 weeks including production and shipping. Chinese manufacturers ship from Fujian or Ningxia ports with similar transit times but often shorter production lead times (2–3 weeks vs 4–6 weeks).
Coconut shell activated carbon is the preferred choice for gold recovery, drinking water purification, and high-purity applications where low ash, high hardness, and consistent micropore structure matter. But the market has hundreds of suppliers making similar claims.

Regardless of which supplier you contact, follow this verification process:
Step 1: Request a TDS and COA — Any legitimate manufacturer can provide a Technical Data Sheet with standard parameters (iodine, hardness, mesh, ash, moisture, pH, bulk density). If they can't, move on.
Step 2: Verify manufacturing origin — Ask for factory photos, location, and ideally a video tour. Confirm whether they manufacture or source. There's nothing wrong with sourcing, but you should know what you're paying for.
Step 3: Start with a trial order — 10–20 tons. Run it through your process. Measure actual performance, not just lab numbers. Lab specs tell you what the carbon can do; field performance tells you what it will do in your specific application.
Step 4: Compare total landed cost — Don't compare FOB prices alone. Factor in shipping, import duties, packaging quality (affects shelf life and handling), and payment terms. A supplier who's $50/ton cheaper FOB but ships in poor packaging or has unreliable lead times costs you more in the end.
Sri Lanka and Indonesia are the traditional leaders in coconut shell raw material quality — their shells tend to be denser with lower natural ash content, thanks to mature coconut palms and favorable growing conditions. However, raw material quality is only half the equation. Activation process control (temperature, steam ratio, residence time) matters just as much. A well-run factory in China using Indonesian shells can match or exceed a poorly-run facility in Sri Lanka. Judge the finished product specs, not just the country of origin.
Ask three questions: (1) Where is your factory located? (A real manufacturer gives a specific address, not just a city.) (2) Can you show factory photos or arrange a visit? (3) Can you produce custom specifications? Trading companies typically offer fixed grades because they buy from third parties. Also check: does their website show production equipment, QC labs, and container loading photos? If it's all stock images and generic descriptions, that's a red flag.
MOQ varies by supplier: large multinationals (Haycarb, Jacobi) typically start at 20+ tons. Mid-tier manufacturers (Huamei, HojeeCarb, Indo German) often accept 10-ton trial orders. Some Indian suppliers may go as low as 5 tons for domestic orders. For international shipments, one 20-foot container (18–20 tons) is the practical minimum for cost-effective logistics.
It can be. Chinese manufacturers like Huamei and HojeeCarb typically use coconut shells sourced from Indonesia and the Philippines — the same raw material regions that supply Sri Lankan factories. The key differentiator is process control: activation temperature, steam ratio, and quality testing. Request a COA from any supplier and compare the numbers. If iodine value, hardness, and ash content meet your specifications, the country of manufacture is secondary to the quality of the finished product.
Depends on your needs. If you only use coconut shell carbon, a specialist like Haycarb or Indo German may offer deeper expertise in that specific material. If you need both coconut shell and coal-based carbon (common in mining operations that use coconut for gold CIL and coal-based for process water), a multi-type manufacturer like HojeeCarb or Jacobi simplifies procurement — one supplier, one relationship, one logistics flow.
