52 Tons Pellet Activated Carbon to the Middle East for VOC Treatment

In Q2 2026, we shipped 52 tons of 4mm coal-based pellet activated carbon to a petrochemical client in the Middle East. The carbon is used in fixed-bed adsorbers for VOC removal from process exhaust — specifically toluene, xylene, and mixed C5–C9 hydrocarbons at 40–60°C inlet temperature.

This is how the order went from first inquiry to delivery.

Client Requirements

The client operates a plastics manufacturing complex with three exhaust streams requiring VOC treatment. Their existing carbon (sourced from a European distributor) was underperforming — breakthrough happening at 60% of rated bed life.

Parametro	Client specification	What we supplied
Carbon type	Coal-based pellet (extruded)	4mm coal-based pellet
Diametro	4.0 mm	4.0 mm (±0.2 mm tolerance)
Numero di iodio	≥900 mg/g	950 mg/g (tested)
Valore CTC	≥60%	65% (tested)
Durezza	≥95%	97%
Umidità	≤5%	3.2%
Contenuto di ceneri	≤12%	9.5%
Densità di massa	450–550 g/L	480 g/L
Quantità	56 tons (3 adsorbers × ~18.5 tons each)	56 tons

The CTC (carbon tetrachloride activity) value was the critical spec — it measures vapor-phase adsorption capacity, which directly determines how long the bed lasts before breakthrough. Their previous supplier was delivering 55–58% CTC, which explains the early breakthrough.

Why Pellet Carbon for VOC Applications

Pellet (extruded) activated carbon is the standard choice for gas-phase VOC treatment because:

Uniform shape = predictable pressure drop across the bed (critical when you're pushing thousands of m³/hr of air through)
Low dust = no downstream particulate issues, cleaner exhaust
Mechanical strength = survives thermal regeneration cycles without crumbling
Consistent packing = no channeling, uniform gas distribution

Granular carbon (irregular shape) creates 20–40% higher pressure drop at the same flow rate and generates more dust during handling and operation. For large gas-phase adsorbers, pellet is always the better engineering choice.

Production & Quality Control

The 52-ton order took 12 days to produce. Our QC process for this shipment:

Raw material stage:

Ningxia anthracite coal selected for high fixed carbon content (≥80%)
Coal pre-tested for ash and volatile content before entering production

In-process checks:

Extrusion diameter checked every 2 hours (4.0 ±0.2 mm)
Carbonization temperature: 600–700°C
Activation temperature: 850–950°C (steam activation)
Activation time adjusted to hit target CTC ≥60%

Finished product testing (every 5-ton batch):

Iodine number (ASTM D4607)
CTC value (ASTM D3467)
Hardness (ASTM D3802)
Moisture, ash, pH, bulk density
Particle size distribution (sieve analysis)

Final COA:

We issued 12 batch COAs (one per ~5 tons) plus a composite COA for the full 52 tons. Client also requested third-party SGS inspection before loading — passed without issues.

Packing & Loading

Item	Detail
Packing	25 kg woven PP bags, palletized
Bags per pallet	40 bags (1 ton/pallet)
Total pallets	52
Container type	2 × 40' HQ containers
Loading per container	26 tons each
Moisture barrier	PE liner inside container
Fumigation	Methyl bromide free (client requirement)

Pellet carbon is sensitive to moisture absorption during transit — especially to the Middle East where port humidity can be high. We line each container with PE sheeting and include silica gel desiccant packs as standard for Gulf destinations.

Logistics & Delivery

Stage	Timeline
Order confirmed	Day 0
Production complete	Day 12
SGS inspection	Day 14
Container loading	Day 15
Port departure (Tianjin)	Day 18
Arrival at destination port	Day 38 (20 days transit)
Client confirmation received	Day 42

Total lead time from order to delivery: 42 days. Production was the bottleneck (12 days) — transit time to the Gulf is fixed at ~20 days from North China ports.

For clients who need faster delivery: we maintain 200+ tons of 4mm pellet carbon in stock at any given time. Stock orders can ship within 3–5 days of payment, cutting total delivery to under 30 days.

Performance Feedback

Six weeks after installation, the client reported:

Bed life extended by approximately 25% compared to their previous European-sourced carbon
Pressure drop 8% lower than previous batch (better uniformity in our pellets)
Outlet VOC concentration consistently below their 20 mg/m³ emission limit
No dust issues during loading or operation

They've since placed a second order (same spec, 52 tons) for their scheduled bed replacement in Q4 2026. Annual consumption: ~112 tons.

Cost Comparison

The client's previous carbon was sourced through a European distributor at approximately $2,800–3,200/ton CIF. Our direct factory price delivered CIF to their port:

30–40% lower than their European distributor price
Same or better specs (CTC 65% vs their previous 55–58%)
Faster reorder (we know their spec, production starts immediately)

The cost saving on 112 tons/year is significant. And the better CTC value means longer bed life — so actual cost-per-operating-hour drops even further.

Specs Summary for VOC Pellet Carbon

If you're running a similar VOC treatment system, here's what to specify:

Parametro	Recommended for VOC	Why it matters
Tipo	Coal-based pellet (extruded)	Low pressure drop, survives regeneration

CTC	≥60% (higher is better)	Directly determines bed life for VOC adsorption
Iodio	≥900 mg/g	General adsorption capacity indicator
Durezza	≥95%	Must survive handling + regeneration cycles
Cenere	≤12%	High ash = less active carbon per kg
MOQ	10 tons	Our minimum order for custom specs

FAQ

What activated carbon is best for VOC removal?

Coal-based pellet (extruded) activated carbon in 3mm or 4mm diameter is the industry standard for fixed-bed VOC adsorption. The key spec is CTC value (carbon tetrachloride activity) — aim for ≥60%. Higher CTC means more vapor-phase adsorption capacity and longer bed life between regeneration or replacement cycles.

How much pellet activated carbon does a VOC treatment system need?

It depends on gas flow rate, VOC concentration, and target outlet concentration. A typical industrial adsorber treating 10,000–30,000 m³/hr of exhaust uses 15–25 tons of carbon per vessel. Most systems have 2–3 vessels (one adsorbing, one regenerating, one on standby). Annual replacement or top-up is typically 15–25% of total bed volume.

What's the difference between 3mm and 4mm pellet carbon?

3mm pellets have more surface area per unit volume (better removal efficiency) but create higher pressure drop. 4mm pellets have lower pressure drop (less fan energy needed) but slightly lower removal kinetics. For high-flow industrial systems (>20,000 m³/hr), 4mm is usually preferred. For smaller systems or when emission limits are very tight, 3mm may be worth the extra pressure drop.

How long does pellet activated carbon last in VOC treatment?

Typically 12–18 months before replacement is needed, depending on inlet VOC concentration and whether the system includes thermal regeneration. With on-site steam or hot nitrogen regeneration, the same carbon can last 3–5 years before adsorption capacity degrades below useful levels. Without regeneration, it's a one-time use with 12–18 month life.

Can you supply pellet carbon with higher CTC for heavy VOC loads?

Yes. Our standard 4mm pellet runs CTC 60–65%. For heavy-duty applications (high VOC concentration or tight emission limits), we produce a high-CTC variant at 70–75% CTC. This requires longer activation time and yields less per batch, so price is approximately 15–20% higher. MOQ 10 tons, lead time 15–18 days.

66 Tons of Gold Recovery Carbon Shipped to South Africa — How a Cheated Buyer Found a Reliable Supplier

When your activated carbon supplier mixes apricot shell into your coconut shell carbon, you don't just lose money. You lose gold. And you lose trust in an entire supply chain.

This is the story of our South African client — a gold mining operation running CIL circuits — who got burned by a dishonest Chinese supplier and how we earned their business with verified, pure coconut shell carbon.

The Problem: Apricot Shell Contamination

Our client operates a gold recovery plant in South Africa using CIL (Carbon-in-Leach) circuits. They'd been buying 6×12 mesh coconut shell activated carbon from another Chinese manufacturer for over a year.

Then performance started declining.

They sent samples to an independent lab. The results:

The "coconut shell" carbon contained apricot shell material — estimated 25–35% per batch
Hardness dropped to 90–93% (below the 98% they were promised)
Gold loading capacity decreased noticeably
Carbon breakage increased in the circuit, causing gold losses to fine carbon

The cost of being cheated:

Reduced gold recovery rates for months before the problem was identified
Wasted carbon replacement costs
Increased fine carbon losses in the circuit
Loss of production time spent troubleshooting

Apricot shell carbon is cheaper than coconut shell. It looks similar in granular form. But it has lower density, lower hardness, and breaks down faster under the mechanical stress of a CIL/CIP circuit. The previous supplier was blending it in to increase profit margins — betting the client wouldn't test it. They were wrong.

How They Found Us

After confirming the contamination, our client needed a new supplier they could verify. A business contact who'd been buying from us for 3+ years made the introduction.

Their requirements were non-negotiable:

100% coconut shell activated carbon — zero blending
Mesh size: 6×12
Iodine number: ≥1100 mg/g
Hardness: ≥98%
Application: Gold recovery (CIL)
Third-party verification before shipment
First order: 66 tons

They also requested:

Factory video call showing raw material storage and production lines
Retain samples from recent batches to other gold mining clients
SGS or BV inspection on the first shipment

We agreed to everything. When your product is genuine, transparency is free.

What We Delivered

Parametro	Client Requirement	Our Delivery
Raw material	100% coconut shell	100% coconut shell (verified)
Dimensione della maglia	6×12	6×12
Numero di iodio	≥1100 mg/g	1120–1150 mg/g
Durezza	≥98%	98.5–99%
Contenuto di ceneri	≤3%	2.2–2.6%
Umidità	≤5%	4.8%

Every batch tested in our lab + third-party verification on the first shipment.

The Shipment: 66 Tons to South Africa

66 tons loaded in containers at port, destination South Africa.

Results after switching to our carbon:

Gold recovery rates returned to expected levels immediately
Carbon lifespan in the circuit increased (less breakage)
Zero disputes since the first delivery
The client has since placed repeat orders

The relationship started because we delivered exactly what we promised. It continues because every batch matches the first.

How to Tell Coconut Shell from Apricot Shell Carbon

If you're buying coconut shell activated carbon, here's how to protect yourself from contamination:

Test	Coconut Shell (genuine)	Apricot Shell (contaminant)
Hardness (ball-pan)	98–99%	85–93%
Apparent density	0.48–0.55 g/mL	0.40–0.45 g/mL
Contenuto di ceneri	2–3%	3–6%
Visual inspection	Dark black, uniform granules, dense	Slightly lighter, more irregular shapes
Water float test	Very few floaters	More particles float (lower density)

Key indicators of blending:

Hardness below 96% on a "coconut shell" product — something else is mixed in
Inconsistent density between batches
Higher-than-expected fine carbon generation in your circuit
Supplier refuses independent inspection

How to Avoid Getting Burned

Test every batch independently — Don't rely solely on supplier COAs. Budget for periodic third-party testing.
Check hardness first — It's the fastest indicator. Pure coconut shell delivers 97%+. If you see 90–93%, investigate immediately.
Request SGS/BV inspection on first orders — Small cost relative to the shipment value.
Ask for factory transparency — Video calls, raw material photos, production videos. Honest suppliers welcome this.
Start with a trial shipment — Test performance in your actual system before committing to large volumes.

FAQ

How can I tell if my carbon has been mixed with apricot shell?

The fastest check is hardness testing. Pure coconut shell activated carbon delivers 97–99% hardness (ball-pan method). If results come back 90–93%, contamination is likely. Density measurement is the second indicator — apricot shell is lighter (0.40–0.45 g/mL vs 0.48–0.55 for coconut). For definitive confirmation, send samples to an independent lab for raw material identification.

Why do some suppliers mix apricot shell into coconut shell carbon?

Cost. Apricot shell raw material is $300–500/ton cheaper than quality coconut shell. Mixing 25–35% into each batch increases profit margin significantly per ton. The visual similarity makes it hard to detect without testing. Suppliers who do this are betting you won't test — or won't test often enough.

Does apricot shell carbon work for gold recovery?

Poorly compared to coconut shell. Lower hardness means more breakage in CIL/CIP circuits, which means gold losses to fine carbon that can't be recovered. Lower density means less gold adsorption per unit volume. It's functional for less demanding applications, but it's not suitable for gold recovery where mechanical strength is critical.

What's the difference between coconut shell and apricot shell activated carbon?

Coconut shell has higher fixed carbon content (73–76%), producing activated carbon with superior hardness (97–99%) and density. Apricot shell has lower fixed carbon (~60–65%), resulting in softer carbon (85–93% hardness) that breaks down faster under mechanical stress. For gold CIL/CIP, coconut shell is the industry standard because circuit conditions demand high abrasion resistance.

Get Verified Carbon for Your Operation

If your current carbon isn't performing — or you suspect contamination — talk to us. We ship pure coconut shell carbon, verified by third-party testing, to gold mining operations across Africa, South America, and Central Asia.

Why Raw Material Source Matters

For gold recovery, the coconut shell itself determines performance.

Indonesian/Philippine shells (used by Chinese factories):

Thicker wall, higher density
Fixed carbon: 73–76%
Higher hardness after activation → less breakage in CIL/CIP → less gold loss

Indian shells:

Thinner wall, lower density
Fixed carbon: 65–70%
Good for trattamento dell'acqua and general applications
For recupero dell'oro, requires careful grade selection

Chinese manufacturers in Fujian and Ningxia import specifically selected thick-shell coconut for gold-grade production. This gives consistent control over raw material quality.

Can Chinese coconut shell carbon match Indian quality for gold recovery?

Yes. Chinese manufacturers importing thick-shell Indonesian/Philippine coconut achieve 73–76% fixed carbon, producing finished carbon with iodine 1100–1300 and hardness 98–99%. The thicker shell source translates to higher mechanical strength in CIL/CIP circuits.

Why is Chinese activated carbon often cheaper?

Scale and supply chain. Larger factories (700–1000 tons/month vs 100–300), domestic equipment manufacturing, lower packaging costs, and competitive energy pricing. For coal-based products, China sits directly on the raw material.

What specs should I compare when evaluating suppliers?

For gold recovery: iodine number, hardness (ball-pan or AARL abrasion), ash content, moisture, and particle size distribution. Request batch COAs using ASTM standards. Don't rely on "typical" specs — ask for actual recent batch data.

600 Tons of Gold Recovery Carbon Shipped in June — How a Burned Buyer Found a Reliable Supplier

Case Study: 600 Tons of Gold Recovery Carbon Shipped in June — How a Burned Buyer Found a Reliable Supplier

When your activated carbon supplier mixes palm shell into your coconut shell carbon, you don't just lose money — you lose gold. Literally.

This is the story of one of our clients in Burkina Faso, how they got burned by a dishonest supplier, and how we earned their trust with 112 tons on the first order.

The Problem: Contaminated Carbon, Lost Gold

Our client operates a gold recovery plant in Burkina Faso using CIL circuits. They'd been buying 6×12 mesh carbone attivo in guscio di cocco from another Chinese supplier for about a year. Production numbers looked fine at first.

Then recovery rates started dropping.

They sent samples to an independent lab. The results:

The "coconut shell" carbon was mixed with palm shell activated carbon — roughly 30–40% of each batch
Hardness was inconsistent (85–90% instead of the promised 98%+)
Gold loading capacity dropped significantly
Carbon was breaking down faster in the circuit, increasing losses to fine carbon

The cost of being cheated:

Estimated gold losses: tens of thousands of dollars per month
Wasted carbon replacement costs
Downtime for circuit troubleshooting
6+ months of below-target recovery before the problem was identified

Palm shell carbon looks similar to coconut shell carbon visually. The supplier was betting they'd never test it. They were wrong — just too late.

How They Found Us

After the fraud was confirmed, our client asked around. A business contact who'd been buying from us for 3+ years made the introduction.

Their requirements were specific:

Prodotto: Carbone attivo in guscio di cocco, 6×12 mesh
Iodine number: 1100 mg/g minimum
Applicazione: Gold recovery (CIL)
Durezza: 98%+ (non-negotiable after their experience)
Verification: Third-party SGS testing before shipment
First order: 112 tons (4 × 40HQ containers)

They were cautious. Understandably. They requested:

Factory video call showing our coconut shell carbonization and activation lines
Retain samples from our last 3 batches to their gold mining clients
SGS pre-shipment inspection for the first order

We agreed to everything. If your product is real, transparency costs nothing.

June Shipment: 600 Tons Total, This Client 112 Tons

June alone, we shipped 600 tonnellate of gold-grade coconut shell activated carbon across multiple clients. This Burkina Faso client took 112 tons — 4 × 40HQ containers loaded at Nansha Port (南沙港).

Yesterday's shipment: 4 × 40HQ loaded and on the water, destination Burkina Faso.

The relationship started because:

Recovery rates went back up immediately after switching to our carbon
Every batch matches the first sample — no surprises
We hit delivery timelines consistently
Zero disputes since the first order

How to Avoid Getting Burned Like This

If you're buying coconut shell activated carbon for gold recovery, here's how to protect yourself:

Test every batch independently — Don't rely on supplier COAs alone. At minimum, check iodine number and hardness. A density/buoyancy test can quickly flag palm shell contamination (palm shell is lighter).
Check hardness numbers carefully — Pure coconut shell carbon delivers 98%+ hardness. If results come back 85–92%, something else is in there.
Request SGS/BV inspection for first orders — $200–400 for peace of mind on a $50,000+ shipment is obvious math.
Visit the factory if possible — See the raw material storage. Coconut shell and palm shell look different before carbonization. If they won't let you near the raw material area, ask yourself why.

FAQ

How can I tell coconut shell from palm shell carbon?

Lab testing is most reliable (hardness, ash content, density). Visual inspection: coconut shell carbon is darker, denser, and has a more uniform granule shape. Palm shell tends to be lighter in color with more irregular shapes. A simple water float test also helps — palm shell carbon has lower density and more pieces float.

Why do some suppliers mix palm shell in?

Money. Palm shell is $500–800/ton cheaper than coconut shell as raw material. Mixing 30–40% palm shell into a batch increases profit margin by $200–300/ton. Multiply that by hundreds of tons and the incentive is clear.

Does palm shell carbon work for gold recovery?

Poorly. Lower hardness means more breakage in CIL/CIP circuits (= gold losses to fine carbon). Lower gold adsorption value means less gold loaded per kg of carbon. It's not worthless, but it's not what you're paying for when you order coconut shell grade.

How long does production typically take?

Standard specs: 7–15 days. Custom specifications (special mesh size, impregnation, acid washing): 15–25 days. These timelines assume raw material is in stock — confirm with your supplier before finalizing delivery schedules.

Activated Carbon Supplier from China: Factory Direct Pricing, Fast delivery

Buying activated carbon from China saves 30–50% compared to sourcing from Western manufacturers. But finding the right supplier — one that actually ships what they promise — takes some homework.

This guide walks you through how to source activated carbon from China: what to look for, what to avoid, typical pricing, and how the process works from first contact to delivery.

Why Source Activated Carbon from China?

China produces over 50% of the world's activated carbon. The raw materials are here (coconut shell from Southeast Asia, coal from Shanxi and Ningxia), the labor costs are lower, and there are hundreds of factories competing on price and quality.

Factor	China Supplier	Western Supplier
Price (coconut shell, FOB)	$2,700–4,500/ton	$3,500–5,500/ton
Price (coal-based, FOB)	$580–2900/ton	$2,200–4,500/ton
MOQ	1–5 tons typical	10–20 tons typical
Production time	7–15 days	4–8 weeks
Custom specs	Flexible	Flexible
Third-party testing	Available (SGS, BV)	Standard

The price gap is real. A ton of gold-grade coconut shell carbon that costs $4,000 from Calgon or Jacobi runs $3200–3,600 FOB China — same specs, same performance.

Types of Activated Carbon Available from China

Tipo	Materia prima	Main Applications	Price Range (FOB)
Coconut shell granular	Coconut shell	Gold recovery, water purification, air treatment	$2,700–3,900/ton
Coal-based granular	Anthracite/bituminous coal	Trattamento dell'acqua, recupero dei solventi, gas purification	$580–1,600/ton
Wood-based powder	Sawdust/wood chips	Decolorization, food & beverage, pharmaceutical	$800–2,100/ton
Coal-based columnar	Coal tar + coal powder	VOC removal, desulfurization, gas masks	$900–2,900/ton
Coconut shell CTC	Coconut shell	Solvent recovery, CTC 60–120%	$2,700–4,500/ton

Most Chinese factories specialize. A coconut shell factory usually doesn't make coal-based, and vice versa. Know which type you need before reaching out.

How to Evaluate a Chinese Activated Carbon Supplier

1. Do They Actually Manufacture?

Red flags of a trader pretending to be a factory:

No factory photos (or stock photos)
Can supply "any type" of activated carbon
Address is an office building, not an industrial zone
Can't explain their production process
No production capacity numbers

What a real factory shows:

Kiln/furnace photos with visible equipment
Specific capacity (e.g., "500 tons/month for coconut shell granular")
Raw material sourcing details
QC lab with testing equipment

2. Can They Provide Third-Party Test Reports?

Any serious supplier should offer:

SGS or BV test reports (not just their own lab)
COA (Certificate of Analysis) per batch
Specific test methods (ASTM D4607 for iodine number, etc.)

If they only provide their own lab results with no third-party option — be cautious.

3. What's Their Export Experience?

Ask:

Which countries have you shipped to?
Can you provide references?
Do you handle export documentation (phytosanitary cert, MSDS, CO)?
Container loading photos from previous shipments?

4. Sample Policy

Good suppliers offer:

Free samples (500g–1kg) with buyer paying freight
Turnaround: 1–3 days for standard products
Custom spec samples: 5–7 days

If they refuse samples or charge excessively — move on.

Pricing Breakdown: What You're Actually Paying For

Cost Factor	Impact
Raw material (coconut shell vs coal)	40–50% of price
Iodine number (higher = more activation = more cost)	15–25%
Hardness requirement	5–10%
Mesh size (custom sizing costs more)	5%
Packaging (25kg bags vs jumbo bags)	2–5%
Testing/certification	2–3%
Profit margin	10–15%

Prices fluctuate with coconut shell supply (seasonal) and coal prices. Q1 usually cheapest, Q3–Q4 slightly higher.

Activated Carbon for Gold Recovery: A Practical Buyer's Guide (2026)

This guide covers what you need to know when sourcing carbone attivo per il recupero dell'oro — specifications, grades, pricing and purchase checks.

How Activated Carbon Works in Gold Recovery

Activated carbon adsorbs gold-cyanide complexes [Au(CN)₂]⁻ from solution. The contact arrangement differs between carbon-in-leach (CIL), carbon-in-pulp (CIP) and carbon-in-column (CIC) circuits:

Process	Brief description	Information for selection
CIL (Carbon-in-Leach)	Carbon contacts slurry during leaching.	Current carbon, slurry conditions, screens and operating concerns.
CIP (Carbon-in-Pulp)	Carbon contacts pulp after leaching.	Current carbon, adsorption conditions and performance concerns.
CIC (Carbon-in-Column)	Dissolved gold is recovered using carbon columns.	Solution conditions, flow, column or bed arrangement and current media.

Loaded carbon undergoes elution to remove adsorbed gold. Thermal reactivation is a separate step used to restore carbon for reuse. Contact conditions and recovery depend on the circuit; the process name alone does not specify a contact time or recovery percentage.

Key Specifications for Gold Recovery Carbon

Review gold recovery carbon specifications for the actual grade under evaluation. A generic gold-grade or water-treatment label does not define a universal specification.

Parametro	What it helps evaluate	What to verify
Gold adsorption	Loading capacity and adsorption kinetics.	Method, units, solution and test conditions.
Mechanical performance	Resistance to particle degradation.	Method, fines and relevant plant evaluation.
Particle size	Screen and equipment compatibility.	Sieve system and particle-size distribution.
Numero di iodio	Supporting product characterization.	Method and grade; not a gold-performance guarantee.
Ash and moisture	Consistency and specification compliance.	Method, basis and batch result.
Apparent density	Loading calculations and consistency.	Method, reporting basis and agreed grade specification.

A water-treatment label alone neither qualifies nor disqualifies a carbon for a gold circuit. Assess the actual grade and relevant test results.

Evaluate gold adsorption and mechanical performance together

Gold loading capacity and adsorption kinetics describe different aspects of performance. Compare results only when the test method, units and conditions are aligned. Iodine number is supporting information and does not replace a gold adsorption assessment.

For results reported as gold activity or a K value, request the definition, method, units and test conditions. Hardness and attrition are separate measurements; neither alone establishes plant carbon loss, gold loss or service life. Particle size also needs evaluation: for example, a 6×12 mesh label should be checked against the sieve system, full size distribution and retention screens.

Compare samples under aligned test conditions

Compare identified samples under aligned preparation and test conditions. Use the current operating carbon as a reference where available, and agree on acceptance criteria before testing. Laboratory results support selection but do not guarantee plant recovery or consumption.

Record sample identity, particle size, preparation, dry or wet basis, test solution, method, temperature, contact time and reference material.

Coconut Shell vs Coal-Based: Which One for Gold?

Coconut shell-based carbons are widely used in gold recovery, but raw material alone does not establish suitability. Compare the specific grades on gold adsorption performance, mechanical behaviour and particle size under relevant test conditions. A coal-based carbon alternative requires the same evaluation; do not select it solely on ore grade or a lower purchase price.

Compare the proposed grades using relevant adsorption and mechanical tests. An unqualified comparison of raw materials, prices or regeneration counts is not a substitute for evaluating the actual carbon.

How to Choose the Right Carbon for Your Operation

1. Your circuit type

For CIL and CIP, share the current carbon, slurry characteristics, screen openings, contact conditions and operating concerns. For CIC, provide solution conditions, flow, column or bed arrangement and the current media. Do not assign a universal hardness threshold from the process abbreviation.

2. Your ore and solution characteristics

Describe changes in feed and solution chemistry, potential fouling and the observed adsorption problem. If preg-robbing is suspected, review the circuit evidence with the responsible process team. Do not assume that a higher iodine number or an acid-washed label resolves the cause.

3. Your reactivation setup

Describe the existing elution and reactivation arrangements and how regenerated carbon is evaluated. Where reactivation is outsourced, include transport and handling in the assessment. Higher initial activity alone does not establish a longer operating life.

4. Price and total cost of ownership

Compare quotations on the same grade, specification, quantity, packaging and delivery terms. Check the quotation date and which transport and handling costs are included. For operating-cost comparisons, use plant-specific carbon consumption, reactivation and disposal data, together with any measured gold losses attributable to carbon. Avoid counting the same loss twice.

When requesting a price for gold recovery activated carbon, identify the grade, required tests, order quantity, packaging, delivery terms and destination. A current, clearly scoped quotation is more useful than a general price range without a date or specification.

Specifications We Supply for Gold Recovery

Huamei’s HMGOLD range includes HMGOLD6000, 7000, 7500 and PLUS. Request the TDS and batch documents for the grade under evaluation, and confirm the required particle size and acceptance tests before purchasing.

Confirm which documents and test results are available for the proposed grade and delivered batch. A sample report does not establish that every batch or every grade has been tested for the same properties.

For a supplier comparison, see the gold recovery carbon brands and suppliers guide. Compare the exact proposed grade and its evidence rather than brand names alone.

Common Problems and How to Avoid Them

Problem: Gold recovery dropping over time

Possible factors include changes in feed or solution conditions, carbon fouling, adsorption conditions and the condition of regenerated carbon. Review plant trends and compare relevant carbon samples with a defined reference using an agreed test method. Confirm the cause before changing the carbon or operating procedure.

Problem: High carbon attrition

Review the carbon grade and particle-size distribution together with screening, transfer and other handling conditions. Compare mechanical test results using the same method. Investigate where fines are generated rather than assuming that one hardness threshold will solve the problem.

Problem: Gold not stripping completely

Review the loaded-carbon condition, solution chemistry and elution operating records with the responsible process team. Evaluate the findings against the plant’s approved procedure and relevant supplier information. Do not apply a universal temperature or time adjustment from a purchasing guide.

Problem: Inconsistent quality between shipments

Compare batch identity, agreed specifications, sampling procedures and test methods before attributing the difference to the raw material. Review the batch documents and retained samples, and follow the agreed retesting and dispute-resolution procedure.

FAQ

What iodine number is best for gold recovery?

There is no single iodine number that establishes suitability for every gold circuit. Iodine number provides supporting information about the carbon, while gold adsorption capacity, adsorption kinetics, mechanical performance and particle size need separate evaluation. Review the specific grade, the test method and your operating requirements rather than treating an iodine value as a recovery guarantee.

How long does activated carbon last in a gold plant?

There is no universal service life or regeneration count. Carbon condition depends on the circuit, handling, fouling, elution and reactivation practices. Track particle degradation, relevant adsorption tests and plant performance over time. Elution and thermal reactivation are different steps, so their cycle counts should not be used interchangeably.

What's the difference between CIL and CIP carbon requirements?

CIL combines leaching and carbon adsorption, while CIP introduces carbon to pulp after leaching. Both require a grade suited to the actual adsorption and mechanical demands of the circuit. Assess the slurry, screening, contact conditions and operating concerns. Do not assign a universal hardness threshold or contact time solely from the process abbreviation.

Can I use the same carbon for gold and water treatment?

Application labels alone are not enough to decide. A carbon sold for water treatment should not be substituted without evaluating the specific grade against gold adsorption, mechanical and particle-size requirements. Compare relevant test data and agree on a trial or acceptance plan where needed. Suitability cannot be determined from iodine number or purchase price alone.

How do I test carbon quality when it arrives?

Check packaging, batch identification and supplied documents against the purchase agreement. Visual inspection is only an initial check. Use an agreed sampling and testing procedure for acceptance, retain samples where required and compare results using the specified methods. Confirm laboratory availability and turnaround rather than assuming a fixed testing time.

What to include in your quotation request

For an RFQ, include the current grade or specification, particle size, required tests and methods, quantity, packaging, delivery terms and destination. State the circuit type and operating concern. If replacing an existing product, provide its technical information for comparison.
