gold leaching stirred tanks

The process design of gold leaching and carbon-in-pulp

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

Improving the process performance of gold cyanide leaching

Cyanide leaching of gold is carried out in very large mechanically stirred tank reactors. The reactor size can be up to 5000 m3. A typical agitator configuration is two downward-pumping hydrofoil impellers, which requires a low mixing power input and results in low

Tank leaching BioMineWiki

Stirred tank bioleaching is mainly applied on refractory gold concentrates with gold concentrations in the range 10-150 g/tonne. In a refractory gold concentrate very fine gold particles are locked into the sulfide matrix and to liberate the gold for subsequent recovery by cyanide leaching the sulfides have to be leached.
