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.

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.
