The Ultimate Guide to Gold Cyanidation

The cyanide slurry after leaching is continuously washed with a double layer concentrator and a filter, and the total gold washing rate is 98% or more. The gold-containing solution (containing 20 g/m3 of gold) was clarified by adding a lead acetate solution, and then the gold was precipitated by a zinc wire replacement precipitation method.
