Working Principle of Washery Coal washing is mainly based on the differences in specific gravities between the coal and impurities present in the coal. Since most of the impurities are heavier than the coal itself the coal is separated from its impurities by designed uses of these differences. Specific gravity of pure coal is between to
METHODOLOGY During August 2009 three samples each of raw coal, clean coal and middlings were collected from Zarand coal washery. Likewise, fine coal Jig water and water from washery tailings pond were collected in precleaned bottles (1 Lit capacity).

Sustainable Management of Coal Preparation explains both the upstream and downstream of coal preparation, stressing clean coal technologies for coal utilization. It not only discusses the sustainability of coal preparation, but also considers the governance and management issues that come with fulfilling economic, social and environmental obligations of a sustainable mining operation.
Coal Washing Plants consist of several subprocessing modules including raw coal preparation (crushing and screening station), pre discharge rejects (rom jig, dense medium vessel/bath, rotary breaker), coal feeding and washing module (jigging or dense medium cyclones) as well as a dewatering module, coal handling module (conveyors, train/truck loading station, stacker reclaimer).
