Options for Washability Analysis of Coal - A ... - ACARP

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.

Float-Sink and Washability Testing | Mining | SGS

We offer you a full range industry standard testing services for the coal and coke industry. Our float-sink/washability tests provide you with the information that you need to fully understand the characteristics of your coal, resulting in more growth from your coal operation.

Coal Beneficiation Process Diagram

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.
