Coal washing is a process that is undertaken in a coal washery or coal preparation plant (CPP) where coal is refined or cleaned of impurities. Coal washing involves using water, mechanical techniques and relies on gravity and the difference of density between coal and it's impurities which are usually more densely packed due to the fact that ...

Raw coal coming from mines is washed to remove the ash contents to make them fit for feeding into boilers, particularly those of steel plants. Barring a few instances, a coal washery does not form part of a coal mine in India. Total installed capacity of washeries in India is around million tonne per year (MTY) as on

The recovery of clean coal from washery rejects is of great significance for protecting China's scarce coking coal resources. The main purpose of this work was to design a deep process that can maximize the recovery of clean coal from a coking coal washery rejects with about 50% ash and test the technical feasibility of the process.

After thermal upgrading, the coal is put through a deep bed stratifier cleaning process to separate the pyrite rich ash from the coal. When fed a typical low rank western coal, the SynCoal process can provide a product with a heating value of up to 12,000 BTU/lb with moisture and ash contents as low as 1% and %, respectively [ 100 ].

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
