Notes on Coal Cleaning

COAL cleaning may be taken as meaning the separation of coal-as-mined into two or more fractions. Coal cleaning includes coal washing, together with any other means used in the ultimate preparation of coal prior to shipment (as coal) . The method of coal cleaning devised for any given mine must be one which is based entirely on the economic results obtainable. The installation of a high-cost and complex washing plant, designed to produce a low-ash dean coal, at the highest possible recovery, may be unsound practice.
