takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide. The leaching of gold can be conveniently represented by the Elsener equation: [1] Although air agitated leach tanks were commonly used in

Leaching Low-Grade Gold Ores
Leaching Low-Grade Gold Ores A dilute cyanide solution is an efficient solvent of gold. However, as in any ot4er leaching process, the solvent has to come in contact with the solid gold particle. Hence, extensive crushing and meticulous two-stage, closed-circuit grinding are needed to liberate the gold particles in the ore.
