Jul 27 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.

Commercial coal preparation however is carried out on wet coal. The density of an air-dry particle in a float and sink liquid is different from the density of a water saturated particle in a washery dense medium. Differences are greatest in lower rank higher porosity higher moisture coals.

Our floatsink analysis can be performed on samples ranging in size from bulk washability samples over 1 ton to bench-scale size samples. We conduct the tests over a range of densities from 1.3 specific gravity up to 2.25 specific gravity and a variety of sizes from coarse to fine coal. We also perform froth recovery testing on finer sizes.
