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.
