· Washing sand and aggregate results in the discharge of dirty water from wet screening decks, sand screws or sand classifiers. The wastewater typically carries fines out to a series of settling ponds. While this is the most common method of treating wash water fines, it is not the most sustainable method. As such, many operations employ equipment such as filter .
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 .

What is soil washing? Soil washing is a technology that uses liquids (usually water, sometimes combined with chemical additives) and a mechanical process to scrub soils. This scrubbing removes hazardous contaminants and concentrates them into a smaller volume. Hazardous contaminants tend to bind, chemically or physically, to silt and clay. Silt and clay, in .
Clean coal technologies enable the efficient, affordable, reliable, and environmentally sound use of fossil fuels, owing to which several environmental agencies and government organizations are taking various initiatives to encourage private/public manufacturers to develop clean coal technologies that reduce emissions from the industrial sector.
The first washing methods were imported from Europe, The "Chance" washer, in which the density differences between coal and mineral matter was exploited to clean raw coal was introduced in 1918. The Chance washer utilized sand and water as a medium. Today, the "heavymedia" process using magnetite is standard for coarse coal cleaning. Attempts to .
