Why Iodine Value Alone Is Not Enough for Gold CIL/CIP
Iodine 1050 and hardness 98% do not predict gold performance. K-value (capacity) and R-value (rate) per GB/T 32992-2016 do - and here is how to use them.
Read Article →Why High Hardness Carbon Prevents Gold Loss in CIP
Attrition turns loaded carbon into fines that leave with the tailings. Why ≥98% hardness (ASTM D3802) protects your gold balance — and how to verify it.
Read Article →CIC vs CIP vs CIL: Choosing Activated Carbon for Gold Recovery
VAT-CIC, CIP and CIL treat the carbon differently. Why hardness ≥98%, platelet content <1.5% and the right mesh cut protect your gold balance in columns and slurry.

A COA is only as good as its method. The five verifiable numbers — hardness ≥98%, platelets <1.5%, mesh, iodine and K/R per GB/T 32992—2016 — and a five-step pre-payment checklist.
