DWORZANOWSKI, M.. The role of metallurgy in enhancing beneficiation in the South African mining industry. J. S. Afr. Inst. Min. Metall. [online]. 2013, vol.113, n.9, pp.677-680. ISSN 2411-9717.

Beneficiation, in the context of this paper, has two distinct definitions. From an economic perspective, beneficiation relates to adding value to a mined raw material. From a metallurgy perspective, beneficiation relates to processes used to upgrade the mined raw material. Clearly then, 'economic beneficiation' is dependent on 'metallurgical beneficiation'. South Africa possesses the world's largest mineral resources by value and is a significant global producer of many mined commodities. Significant metallurgical beneficiation of ores does occur in South Africa. The role of metallurgy in economic beneficiation will be examined in terms of current practice and the potential for expansion. South Africa's main mining commodities will be covered - namely gold, platinum, coal, iron ore, manganese, chromium, vanadium, copper, nickel, titanium, zirconium, uranium, and diamonds.
