How to Fix Agitator Mixer Problems in a Gold Leach Circuit

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.
