2019-10-07 · 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 ...

2013-01-01 · The objective of coal preparation is to separate valuable coal from unwanted mineral matter. Separation is achieved by exploiting differences in the physical (e.g., density, size, shape) and physico-chemical (e.g., wettability) properties of coal and mineral matter. Ideally, the plant-wide separation should be as efficient as possible in order to maximize coal yield at a given quality ...
