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