    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 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.
