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#176; C for 4 hours. Similarly, pretreatment of the ore pulp with 35 lb chlorine per ton at 24#176; to 30#176; C and 15 hours reaction time resulted in 89pct gold extraction by subsequent cyaanidation.

The Au extraction profile was highly reproducible up to 144 hours in the second test, where Au extraction was % after 96 hours at 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
Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.
