Leaching is a hydrometallurgical method that permits the beneficiation of gold ores from deposits which would else be uneconomic because of their fine gold distribution or their relatively low gold grades. Leaching processes, however, are not limited to such ores. The chlorination process, which is obsolete by now, used chlorine gas that was

Cyanidation leaching is the primary means of recovery of fine gold and silver. In this process, solutions of sodium or potassium cyanide are brought into contact with an ore which may or may not have required extensive preparation prior to leaching. Gold and silver are dissolved by cyanide in solutions of high pH in the presence of oxygen.
