Opportunities for fine coal utilisation, CCC/185

Coal is prepared to meet end-user requirements such as limits on the proportion of fine coal and ash forming minerals in the product. Preparation methods leave residues of fine material which can have a wide range of compositions from a good coal product to very high ash, surface moisture and sulphur contents. Regardless of composition, at the time of generation of these residues no market for them existed and so large amounts (estimated as about 58 Gt) have been deposited around the world in heaps or in slurry impoundments. Changes to the value of coal and developments in coal preparation and utilisation technologies have enabled increasing amounts of these materials to be recovered and used. The report provides an overview of the resource and opportunities for utilisation.
