Coal drying. Coal preparation plants that employ fine coal cleaning by froth flotation can produce an unacceptable amount of moisture in the product. Thermal drying, in which the wet coal is dried in the hot gas generated by a coal-or gas-fired burner, is used in some plants to reduce the moisture content. Refuse and tailings management.

Pyrite is removed from coal by means of a two-stage froth flotation process. In the first stage, coarse pyrite is removed as underflow in a conventional froth flotation operation. In the second stage, the froth product from the first stage is subjected to froth flotation using a coal flotation depressant and a pyrite flotation collector, thereby removing a substantial proportion of fine pyrite.
