In a standard float-sink analysis, set amounts of the representative coal sample are crushed to a specified particle size and placed in liquids of known density or across a range of densities. Coal has relatively low density or specific gravity (1.2 to 1.5) compared to other rocks such as shale (2.4 to 2.8) or minerals such as pyrite (4.9 to 5.2).

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 ...

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%.
