Miners, mining materials and equipment are transported deep underground via the mine cage in the vertical shaft, which can go to depths of up to 3.5km below the surface. Open-pit gold mining also takes place in South Africa. This is a mining technique which excavates at the surface to extract ore.

The processing of gold-copper ores (higher values of gold than copper) typically follows the route of cyanidation, whereas for copper-gold ores (higher copper than gold values) the process route is typically flotation and smelting. In the latter case, gold credits are obtained from smelting the copper

The Gold Mining Process. In addition to cyanide processing, gold ore is also processed with gravity separation. Advanced technology has enabled the amount of gold mined and processed to steadily increase over the years. For example, the worldwide production of gold in 2006 was 2360 metric tons. As of 2013, that number had climbed …
