4.2 Procedure B—Describes a washability procedure for coal fractions composed of particles of coal that are smaller than the specified, predetermined size chosen in 4.1. These coal fractions will be referred to as fine-coal fractions. 4.2.1 Each fine-coal size fraction is separated into two distinct specific gravity fractions by placing a portion of the fine-coal sample into a float ...

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.

From the washability curves obtained, plateau was not reached in the ±0.1 distribution curve of Enugu coal; this suggests that Enugu coal is difficult to clean. This difficulty is as a result of the presence of near gravity materials in Enugu coal. For design of coal washing plants for use in coal-based power plants, the washability curves give the specific gravity value, ash content and ash ...

1.2 While, in general, this test method has useful application in determining the washability characteristics of low-rank coals, in the strictest sense, it is not necessarily the most technically correct test method to determine washability characteristics of low-rank coals because of problems relative to the loss of moisture through drying during sample preparation and analysis.
