Ore processing. Ore mined is treated and smelted at Mponengs gold plant. The ore is initially ground down by means of semiautogenous milling after which a conventional gold leach process incorporating liquid oxygen injection is applied. The gold is then extracted by means of carbon in pulp (CIP) technology.
In ores, gold occurs mainly in the free (native) state and only very rarely forms minerals with selenium, tellurium, antimony, and bismuth. Pyrites and other sulfides frequently contain an admixture of gold, which is extracted in the processing of copper ore, complex ores, and others.
