Cyanide Leaching | Mining | SGS

Activated carbon effectively removes the gold from the cyanide, as the gold is adsorbed into the pores in the carbon. This has spawned technologies such as CIP (carbon-in-pulp), CIL (carbon-in-leach) and CIC (carbon-in-columns). More recently, SGS has lead the gold processing industry with the development of resin-based technologies.

Effect of Oxygen on Gold Leaching

In simplified terms, the Effect of Oxygen on Gold Leaching can be summarized in saying: The dissolution rate of gold in alkaline cyanide solutions under atmospheric conditions, and at practical cyanide levels, is directly proportional to the dissolved oxygen concentration. The rate of dissolution of gold in alkaline cyanide solution is dependent on a number of factors, principally the solution ...
