DMRE > Mineral Policy & Promotion > Beneficiation Economics
The concept of beneficiation is not new in South Africa, but it took major steps forward during the 1990s. During this period, the South African mining sector changed from being a predominantly primary commodity exporter to becoming a world exporter of processed minerals. South Africa, for example, produced 2.9Mt of ferrochrome (used in ...

Fluidized Bed Dry Dense Medium Coal Beneficiation
Abstract— Coal beneficiation in South Africa is currently conducted mostly on a wet "float and sink" basis. This process is heavily water intensive and also potentially polluting. Dry beneficiation alternatives are being sought. The alternative of dry dense medium beneficiation using a fluidized bed was investigated.

Dense-medium beneficiation of fine coal revisited
Introduction. Dense-medium beneficiation of fine (minus 0.5 mm) coal is not a new concept and has been used in South Africa previously. The dense-medium fine coal plant at Greenside Colliery operated for almost 18 years and, despite proving a difficult plant to operate, did succeed in producing a fine coal product with a low ash content of 7%.

TECHNOLOGIES IN USE FOR THE PROCESSING OF FINE COAL
The value of the fine coal necessitated the selection of the correct equipment for the gravity beneficiation of this coal. On the other hand, fine coal might be unwanted; it all depends on the coal, the market and the decision makers. Each technology in use for the processing of fine coal therefore has its own place in the process flow diagram.
