The most famous gold placer deposits occur in the Witwatersrand basin of South Africa. Residual mineral deposits can form when weathering processes remove water soluble minerals from an area, leaving a concentration of less soluble minerals. The aluminum ore, bauxite, was originally formed in this manner under tropical weathering conditions.

Origin and depositional history of platinum-group minerals
202251 Exploitation of the placer deposits began in 1984, producing about 24 metric tons of platinum or 40% of the resource (Shcheka et al., 2004). Average grade of the placer deposits is 1.6 g/m 3 PGEs. Drainages within the intrusive body have grades of 4 g/m 3 but are reduced to about 0.5 g/m 3 downstream over a total length of about 50 km.
