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%. No other ...

Beneficiation of coal is a water intensive process, and the water is recovered in downstream operations in the high rate thickener (HRT) and vacuum belt filtration (VBF). Clean coal particles entering the HRT have an inherent tendency to enter the overflow because they are extremely fine and hydrophobic. Hence, flocculants …

Coal is one of the most controversial sources of modern energy. In America about 29% of the electricity we use is generated by power plants that burn coal. Coal is a plentiful but non-renewable resource. But coal is a form of carbon and when we burn coal we release carbon into the atmosphere, which contributes to global warming.
