gold recovery using carbon

Function Of Activated Carbon For Gold Mining Blogger

Carbon is very actively used in the process of recovery of dissolved gold, either by introducing direct to the CIL (carbon in leach) or CIP (carbon in pulp) tanks after leaching. Activated carbon adsorbs dissolved gold from gold leach pulp complex to be absorbed through the pores of the carbon.

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.

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.

A theoretical study of the carbon in pulp process for gold

The carbon in pulp process for gold recovery involves treatment with cyanide under aerobic conditions at high pH, to give the Au(CN) 2 ion, which is then recovered by adsorption on carbon, followed by elution of the Au(CN) 2 in caustic solution and electrowinning of the gold. In this study, the stability of models of the carbongold
