Improving the process performance of gold cyanide

Cyanide leaching of gold is carried out in very large mechanically stirred tank reactors. The reactor size can be up to 5000 m. A typical agitator configuration is two downwardpumping hydrofoil impellers, which requires a low mixing power input and results in low shear rates inside the reactor. This results in an economically efficient process with low levels of carbon attrition, to thus ...
