Gold extraction of 90 pct was achieved by cyanidation of carbonaceous ore that had been pretreated with 20 lb per ton sodium hypochlorite at 50° C for 4 hours. Similarly, pretreatment of the ore pulp with 35 lb chlorine per ton at 24° to 30° C and 15 hours reaction time resulted in 89-pct gold extraction by subsequent cyaanidation.

The Au extraction profile was highly reproducible up to 144 hours in the second test, where Au extraction was 77.88% after 96 hours at 1.10 kg/tonne ore NaCN consumption. After 96 hours, the % Au extracted tended to decrease. Normally, maximum Au extraction % corresponds to the point where the NaCN leaching of gold comes to the

African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation. The ore is first reduced in size (typically 80% passing 75µm) to ensure that all non-refractory gold is readily accessible for cyanide leaching. There are several variations of comminution circuits used in the

The final gold product of Tau Lekoa mine has a low fineness. This is caused by high concentration of bases metals in the reefs. Some of these base metals together with gold are leached with cyanide and are loaded into carbon. If not adequately controlled, they may elute with gold and contaminate the final product in the electrowinning process.
