How to Fix Mixing Problems in a Gold Leach Circuit

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.

2016-9-7  All-gold ores can usually be treated with much weaker solutions than silver-gold and silver ores. For the latter the writer has found that the maximum extraction can rarely be obtained with a treatment solution of less than 0.1% KCN or 2 lb. per ton of solution, while if time of treatment is unduly limited, even higher strengths are advisable.
