A practical guide to coconut-shell activated carbon for gold recovery: iodine value, hardn
Nutshell Gold Recovery Carbon
The cost-effective heap-leaching carbon — apricot-shell based, iodine up to 1000.
Why Choose This Grade
- ✓Lower cost than coconut — apricot-shell feedstock cuts cost in high-tonnage heap-leach circuits
- ✓Iodine up to 1000 — leading specs in the nutshell-carbon price band
- ✓Hardness ≥95% — sufficient for heap-leach circulation
- ✓Same 6×12 mesh system — drop-in swap with coconut gold carbon
Product Description
Made from premium nutshell (mainly apricot shell) via physical activation, designed for heap-leach recovery of gold and other precious metals. Lower feedstock cost than coconut carbon makes it ideal for low-grade ore and high-tonnage heap-leach operations, while iodine up to 1000 keeps gold loading competitive. The cost-effective choice for maximum recovery from low-grade ore.
