Introduction to Cyanide Gold Mining

Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material. Activated carbon is used to adsorb the gold out of solution. Because the cyanide ion forms very strong complexes with gold, it is the gold cyanide complex that is loaded onto the carbon rather than being deposited as metallic gold.

Gold Mining Process Development Denver Mineral

Gold cyanide is adsorbed into the pores of activated carbon, resulting in a process solution that is devoid of gold. The loaded carbon is heated by a strong solution of hot caustic and cyanide to reverse the adsorption process and strip the carbon of gold. Gold is then removed from the solution by electrowinning.

Sabinet The mechanism of the adsorption of gold cyanide

X ray photoelectron spectroscopy showed that the adsorption of gold cyanide on carbon in the presence or absence of electrolytes and acids proceeds by

Removal of heavy metal ions from wastewaters A review

Heavy metal pollution has become one of the most serious environmental problems today. The treatment of heavy metals is of special concern due to their recalcitrance and persistence in the environment.

The leaching and adsorption behaviour of gold ores

adsorption onto activated carbon, these effects include competing metal cyanide complexes, preg robbing and the mineralogy of the ore. This thesis considers these areas from an experimental and modelling viewpoint. In this research it is shown that a variety of metal cyanide species can be used to leach gold from certain refractory ores.
