Gold crossed $3,200/oz in 2026. Every time gold spikes like this, our order books change within 60 days. Not because mines suddenly need better carbon — but because operations that weren't economically viable at $1,800 gold suddenly make money at $3,200.
The result: tailings reprocessing projects restart, marginal ore bodies get developed, and carbon consumption per mine increases as plants push throughput. Here's what's happening on the ground and what it means for carbon selection.
The connection is straightforward:
| Gold price level | What becomes viable | Carbon impact |
|---|---|---|
| $1,800–2,200/oz | High-grade primary ore only | Baseline carbon consumption |
| $2,200–2,800/oz | Medium-grade ore + some tailings | 15–30% increase in carbon orders |
| $2,800–3,200+/oz | Low-grade ore + tailings + marginal deposits | 40–60% surge in new carbon demand |
At $3,200 gold, a tailings dump with 0.3 g/t residual gold becomes profitable to reprocess. A deposit with 1.2 g/t that no one would touch at $1,800 suddenly justifies a CIL plant. Each of these new or restarted operations needs activated carbon — typically 50–200 tons for initial fills, plus 20–50 tons/year ongoing.
Tailings are yesterday's waste at today's gold price. When gold hits record levels, miners look at their tailings dams and see cash sitting in the ground.
Why tailings projects consume more carbon per ton of ore:
Typical tailings reprocessing carbon specs:
| mParaeter | Tailings application | Primary ore (comparison) |
|---|---|---|
| Mesh size | 6×12 or 6×16 | 6×12 |
| Iodine number | ≥1100 mg/g | ≥1050 mg/g |
| Hardness | ≥98% | ≥98% |
| Preferred type | Coconut shell | Coconut shell |
| Carbon loading target | 3,000–8,000 g Au/t C | 8,000–20,000 g Au/t C |
| Elution frequency | More frequent (lower loading) | Standard (higher loading) |
Tailings circuits often specify slightly higher iodine and hardness because the carbon sees more elution cycles per year — it needs to survive repeated thermal stress without degrading.
"Marginal" means the deposit exists but wasn't worth building a plant for at lower gold prices. At $3,200/oz, the math changes:
Each new operation = new carbon demand. And these smaller/newer operations often order in batches of 20–50 tons rather than the 100+ ton bulk orders from established mines — meaning more customers, more orders, more logistics coordination.
Not all gold ores treat the same, and the 2026 gold rush is bringing diverse ore types into production:
| Ore type | Key challenge | Carbon requirement |
|---|---|---|
| Free-milling oxide | Easy leaching,
straightforward |
Standard 6×12,
iodine ≥1050 |
| Refractory
sulfide |
Needs pre-oxidation (POX/BIOX) | Higher hardness (≥98%),
handles aggressive leach chemistry |
| High-copper
ore |
Copper competes for carbon adsorption sites | Higher capacity carbon
(iodine ≥1100), more frequent elution |
| Carbonaceous (preg-robbing) | Natural carbon in ore steals gold | Ultra-high activity carbon to
out-compete natural carbon |
| Tailings
(mixed) |
Variable grade, fine particles | High hardness + consistent
quality for stable recovery |
The trend we're seeing in 2026: More inquiries for high-specification carbon (1100+ iodine, 98%+ hardness) because the new wave of projects tends to be either:
Standard "good enough" carbon that works for easy oxide ores doesn't cut it for these applications.
Where is the demand surge actually happening?
| Region | What's driving it | Carbon demand trend |
|---|---|---|
| West Africa (Ghana, Mali, Burkina Faso) | Tailings reprocessing + new marginal deposits | +40% YoY |
| East Africa (Ethiopia, Tanzania, Sudan) | New CIL plants + artisanal-to-industrial transition | +50% YoY (from lower base) |
| Central Asia (Uzbekistan, Kazakhstan) | Refractory ore projects restarted | +25% YoY |
| South America (Peru, Colombia) | Small-scale CIP plants in marginal deposits | +30% YoY |
| Australia | Tailings retreatment at legacy sites | Steady, high-spec focus |
Our factory's output allocation to gold mining has increased from ~35% of production in 2024 to over 50% in 2026 — almost entirely driven by tailings and marginal ore projects ordering for the first time.
When everyone orders more carbon at the same time, supply tightens. What we're seeing:
What smart buyers are doing:
If you're operating or planning a gold recovery circuit in 2026:
Act now on carbon procurement. Every month gold stays above $3,000, more marginal projects commit to production. That's 6–12 months of new customers entering the activated carbon market who weren't there before. Supply is not infinite.
Specify higher. The projects coming online in 2026 disproportionately need high-spec carbon (iodine ≥1100, hardness ≥98%). If you're running a standard operation, your supply isn't threatened yet. If you need premium grades, secure supply now.
Consider direct factory relationships. Distributors add 20–40% margin. In a tight market, factory-direct customers get priority on production scheduling.
| Fact | Detail |
|---|---|
| Monthly production | 700+ tons (all grades) |
| Gold-specific output | 350+ tons/month coconut
shell 6×12 |
| Raw material secured | Annual contracts with Indonesian/Philippine
/Sri Lankan shell suppliers |
| Current lead time | 10–15 days production,
ship immediately |
| Quality guarantee | Every batch COA + optional
SGS pre-shipment inspection |
| Export coverage | 30+ countries, established logistics to Africa,
Central Asia, South America |
We anticipated this demand increase 12 months ago and secured raw material supply accordingly. We can still accommodate new customers — but production slots are filling faster than any year prior.
Higher gold prices make previously uneconomical gold deposits and tailings viable to process. Each new operation that starts (or restarts) needs activated carbon for its CIL/CIP circuits — typically 50–200 tons initially plus 20–50 tons annually. The carbon demand increase lags gold price increases by roughly 3–6 months (time to plan, build/restart, and begin processing).
Tailings operations typically require coconut shell activated carbon, 6×12 mesh, with iodine ≥1100 mg/g and hardness ≥98%. The higher specs are needed because tailings circuits run more elution cycles per year (lower gold loading per cycle due to lower grades), so the carbon faces more thermal and mechanical stress.
It's tightening but not critically short — yet. Quality coconut shell raw material is finite, production capacity has limits, and when demand rises 40–60% across the industry, lead times extend. The risk is primarily for buyers who don't plan ahead. Those ordering on spot basis 2–3 weeks before needing delivery will face delays or quality compromises.
Initial carbon fill for a CIL circuit depends on plant size. A 2,000 tpd plant typically needs 80–120 tons of carbon in the circuit. A 5,000 tpd plant needs 150–250 tons. Annual replacement (attrition losses + degradation) runs 15–25% of the initial fill. Tailings projects at maximum throughput may replace 25–30% annually due to harder operating conditions.
Yes. The carbon that works perfectly for free-milling oxide ore at 3 g/t may underperform on refractory sulfide ore at 1.5 g/t. Key differences: refractory ores after oxidation produce more aggressive leach solutions — you need higher hardness (≥98%) to survive the chemistry. High-copper ores need higher capacity carbon (≥1100 iodine) because copper occupies adsorption sites. Get carbon specs matched to your specific ore type and circuit conditions.
Gold prices are driving a structural demand increase that isn't going to reverse until gold drops below $2,500.
