Cyanide Leaching Of Gold Mine

Generally, the recovery for cyanide leaching of sulfide or refractory ores is no better than 30 , which is not a worthwhile venture. The use of alkalies such as calcium oxide, will prevent theposition of cyanide in solution to form hydrogen cyanide gas. It reduces the volume of cyanide required to leach the gold or silver.

Effect of Gold Cyanide Leaching Is Poor? Here Is

During the cyanide leaching, it is difficult for cyanide solution to contact with gold ores, so the rate of gold leaching is not high. Solution: Under a certain degree of monomer dissociation, aqueous solution oxidation method, aqueous solution chlorination method and bacterial oxidation method can be adopted for the gold ore containing small amount arsenic.
