The process DRDGOLD

The metallurgical process. The Brakpan plant uses carbon in leach and flotation and finegrind as part of the retreatment process. Carbon in pulp was used for a time but the CIP circuit has been converted to CIL to optimise leaching and adsorption. The flotation and finegrind circuits were constructed and commissioned during FY3 and FY4 in order to recover more gold from the tailings.
