2020/08/09· Gold mining is either load (hard rock) or placer (loose gold that has separated from rock through natural processes). For the recreational prospector, the two most popular forms of gold prospecting are gold panning for placer gold or using a metal detector to find nuggets (also known as shooting for nuggets).

2020-2-28  The main mining method is longwall. TauTona shares a processing plant with Savuka. The plant uses conventional milling to crush the ore and a CIP (carbon in plant) to further treat the ore. Once the carbon has been added to the ore, it is transported to the plant at Mponeng for electro-winning, smelting and the final recovery of the gold.
