Coal preparation depends on the mineral''s properties and its intended use. It may require only simple crushing or it may need to go through a complex treatment of washing and processing to reduce impurities. To remove impurities, the raw ROM is crushed and then separated into various size fractions. Larger material is usually treated using DMS.

Introduction to Mineral Processing

Particle Size. The particle size to which the ore is ground depends on the nature of the ore. The grind must be fine enough to liberate the mineral grain from associated rock, but producing too small a particle size is both expensive and detrimental to recovery. Froth flotation is generally limited to size fractions between roughly 65 and 100 mesh.
