The first diamonds discovered in South Africa were from alluvial deposits. Today, industrial alluvial mining involves building a large wall to collect the water in one area. Diamonds are often found in the gravel layer, which collects under layers of other material, such as mud, clay and underwater plantlife.

South Africa has the secondlargest reserves of uranium in the world. The Nuclear Fuels Corporation of South Africa (NUFCOR) started processing uranium as a byproduct of gold mining in 1967. Most of the uranium produced as a byproduct of gold mining is concentrated in the golf fields of the Witwatersrand area.
Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world''s deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers. The first such mine to receive air ...

Various methods such as gravity concentration, flotation, panning, pyrometallurgy, cyanidation etc are available for the extraction of gold metal from its ores. Amongst these methods, cyanidation is the most common method used in the leaching of gold from the ore. ... China, South Africa, Australia and United States are the largest producers of ...
In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the AuAg tellurides, and very finegrained gold (<10 µm) locked in sulfides. Other types of problem gold ores include coppergold ores and pregrobbing carbonaceous ores.
The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in .

Gold mining in South Africa typically involves methods such as panning, sluicing, dredging, hard rock mining, and byproduct mining. For most effective gold mining in South Africa, the method used is hard rock mining, since reserves are typically fully encased in rock deep underground.
Gold mining in South Africa South Africa''s gold industry rising again After more than a century of gold mining in South Africa, the US Geological Survey''s latest estimate still ranks South Africa as the custodian of the world''s second largest gold resources at 6,000 tonnes second only to Australia.
Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earth''s crust. It occasionally is found as nuggets as large as 12 millimetres ( inch) in diameter, and on rare occasions ...
In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand. ... (in the Limpopo Province) there is evidence of gold mining in South Africa as early as 1200. Today, South Africa is a world leader in the technology of gold mining.
