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%.
Coal beneficiation is the process by which the combustible fraction of coal is separated from inert (ash) material to produce a product of improved properties, generally with a higher calorific value (CV). The principle of this separation is that the combustible fraction has a lower density than the ash fraction, and treating the coal in a ...
Abstract. To comprehend the varied composition, properties and uses coal ash, it is important to begin with an understanding of the coal from which it is derived. Coal is essentially an assemblage of organic and inorganic material that transforms over geologic time into a relatively high energy density fuel through the process of coalification.
