Initial leach temperatures of 40°C were adopted with the view to use waste heat from the bacterial oxidation circuit which operates at a similar temperature. 'Heated leach' tests conducted on CIL feed at 40°C immediately showed benefits with a step increase in CIL recoveries over both plant and previous testwork results and provided the ...

The Fosterville Gold Mine processes ore that contains disseminated gold within arsenopyrite and pyrite minerals as well as native carbon in the form of bituminous coal. This native carbon causes significant gold loss through "preg-robbing" in the carbon-in-leach (CIL) circuit, resulting in recoveries as low as 35%. To address this, the mine installed a heated leach circuit to treat CIL ...
