• How to Fix Mixing 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 3040% solids by weight with the solid particles being less than 100 microns () in size. Air or oxygen is often bubbled through the slurry to improve the leaching reaction. In this case there were 12 leach tanks that were 9m ...

    The basecase model of the circuit used for calculation involved four agitated leach tanks, arranged in series. Sulphuric acid, water, and ore were added to the first leach tank. The leaching of both copper and iron were modelled using ratebased equations. The rate expression used is shown as Equation [3]: k[H 2 SO 4][CuO (s)] [3] where
