The term, Alluvial Mining is based from the Latin word of "Alluvius" – which roughly translated means "to wash against".This provides a better understanding of the actual process of alluvial diamond mining which is done in riverbeds and beaches where diamonds have been washed out of their host rock and transported by erosion.
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 below the surface. Openpit gold mining also takes place in South Africa. This is a mining technique which excavates at the surface to extract ore.
