Gold ore serves as the vital raw material that forms the basis of the entire gold refinery process, leading to the production of pure gold. Its significance lies in being the primary source from which gold is extracted and transformed into the precious metal we hold in high esteem. Gaining an understanding of gold ore and its properties is ...

Abstract. South Africa's economy is partly built on gold (Au) mining; this mining sector is an essential foreign exchange earner, with Au accounting for more than one-third of exports. But due to a decrease in high-grade gold ores, the need, therefore, arises to investigate ground-breaking approaches for sustainable processing of complex …

There are about 20 or more gold ore bodies (quartz pebble conglomerates) that have been mined, or are currently in production. Furthermore, the Bushveld Complex of South Africa is estimated to contain about 70% of the world's reserves of platinum group elements. The most important platinum ore bodies are the Merensky Reef and the UG2.

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, …

1.. IntroductionGold deposits in the Vaal River region, South Africa, also contain uranium-bearing minerals. Although the uranium content of the ore is very low by international standards (it averages only 0.3 kg U 3 O 8 /t), recovering uranium as a by-product of gold production improves the overall processing economics. The benefit is …
