Leaching Tanks

2021-6-29 · A cyanide leaching circuit usually consists of large agitated tanks for mixing mineral slurry with cyanide in order to extract gold. Typically, the slurry consists of 30-40% solids by weight with the solid particles being less than 100 microns (0.1mm) in size. Air or oxygen is often bubbled through the slurry to improve the leaching reaction.

gold cyanide leaching

2021-9-14 · When the cyanide content reaches 0.15%, the dissolution rate of gold is independent of the cyanide content, even decreases (due to cyanide hydrolysis). In the gold cyanide leaching process, the oxygen or other agents (such as H2O2, CaO2, Na2O2, KMnO4, and Cl2) can be used as oxidants, but most cyanide leaching concentrators choose to fill air ...

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, …
