6th Wave Innovations Corp IXOS174; for Ore Processing

The vast majority of gold mines currently use coconut based activated carbon (AC) for recovery of gold from cyanide leach solutions. These mines typically use carbon in pulp, carbon in leach, and, to a lesser degree, carbon in column systems to extract gold.

Gold extraction

A quot;refractoryquot; gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold.

Gold Mining Process Development Denver Mineral Engineers

used when native carbon is present in the gold ore. This native carbon will adsorb the leached gold and prevent its recovery. This phenomenon is referred to commonly as preg robbing. The carbon added in CIL is more active than native carbon, so the gold will be preferentially adsorbed by carbon that can be recovered for stripping.
