The Metallurgy of Cyanide Gold Leaching

Oct 20, 2014· Refractory Ores/Solid-Solution Gold: In some ores, Au can be locked inside the sulphide mineral matrix of the ore (so called solid solution), and the cost for the energy required to grind and liberate is simply too high to be viable These are “refractory ores” and require a chemical, not simply physical, process to liberate gold from the.

Gold Mining Process Development

REFRACTORY ORE PROCESSING The common definition of “refractory” gold ores, are those ores that do not allow the recovery of gold by standard gravity concentration or direct cyanide leaching One major category of refractory ores are gold values contained within the crystalline structure of sulfide minerals such as pyrite and arsenopyrite.

Cyanide Leaching Of Gold

Carbonaceous gold ores can have the carbon adsorb the gold onto its surface, and as a result will not be recovered from the pregnant solution Leaching gold from sulfide ores is difficult, at best Generally, the recovery for cyanide leaching of sulfide or refractory ores is no better than 30%, which is not a worthwhile venture.

The Mining Process

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver This process removes 93% of the gold and 70% of the silver.
