The ball mill, in closed circuit with a classifier, is fed with ore, cyanide, lime, and carbon as charcoal. The classifier overflow is thickened and then agitated. The gold is dissolved by the cyanide solution and then its soluble gold-cyanide compound is absorbed by the finely divided charcoal. Flotation then recovers the charcoal.

To that end, batch tests were used to investigate the effect of feed tailoring in ball milling using a South African gold ore. Narrow-size feeds of the ore were prepared and milled with 20 and 30 mm sets of single-size balls using the one-size fraction method. From the experimental data obtained, milling parameters of the ore were determined ...
