coal washability and calculations

Float-Sink (Washability) Test, Coal Analysis, Kentucky ...

27/07/2020  In washability tests, coal samples are separated into float and sink fractions in liquids of increasing density. If a coal sample will be sent to a preparation plant that uses a fixed density for separating coal from rock and minerals, then a single float-sink test may be done on a sample at the fluid density used in the plant. The single float-sink test defines the relative amount of float ...

Options for Washability Analysis of Coal - A Literature

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.
