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.
Coal Beneficiation Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: – Drydeshaling: Noncoal or shalycoal is removed without using any liquid media.
