2020-4-5effects. Diagnostic leaching was used to show that mineralogy was not an important factor in the enhanced gold extraction in the presence of activated carbon for the ores. Kinetic models were developed for the leaching of gold from the ore adsorption onto activated carbon and preg-robbing at the ore surface. A variable order empirical
Gold production in South Africa is projected to continue its decline in future and prospects for discovery of new high-grade deposits are limited. Many of the mining companies have resorted to mining and processing low-grade and complex gold ores. Such ores are technically challenging to process which results in low recovery rates excessive reagent consumption and high operating costs when
