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

2009-8-27  The gold aurocyanide complex in the aqueous phase is readily adsorbed onto the activated carbon. By the time the pulp leaves the last tank in the adsorption cascade the concentration of gold in the aqueous phase is typically between 0.001 and 0.02 ppm with a value of 0.01–0.005 ppm regarded as a practically achievable value for most well-

Leaching Tanks - Sepro Mixing Systems

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.

How to Fix Agitator Mixer Problems in a Gold Leach Circuit

This design problem caused solids to build up around the walls and bottom of the leach tank, reducing the effective size of the tank and lowering the actual leaching time for the active slurry. This reduction in leach time ultimately resulted in lower gold recovery. To get more agitation, the agitator impellers were sped up.
