1.1 This test method describes procedures for determining the washability characteristics of coarse-coal fractions and fine-coal fractions. Each sample being tested can have more than one coarse-coal size fraction and more than one fine-coal size fraction (see Annex A1).Each such size fraction has an upper size limit and a lower size limit, neither of which overlaps with the next larger nor ...

The Australian Coal industry needs to find an alternative to the heavy organic liquids used to produce its coal washability analyses. Indeed, the existing Australian Standard for the Float and Sink analysis of coal is likely to be phased out over the next five years, and thus the matter needs to be urgently addressed to allow time to establish a new approach, with a new standard.

Many breakers and washeries efficiently handle the coarser sizes, but waste the coal fines. This problem is assuming major importance due to the increase in the amount of coal fines being produced by the mechanization of coal mining. Flotation offers a very satisfactory low-cost method for recovering a fine, low ash, clean coal product at a profit.
