  • What is Coal Washing? Definition from Safeopedia

    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 thatCoal washing Coal that comes from a mine is a complex mixture of materials with a large variety of physical properties In addition to the coal itself, pieces of rock, sand, and various minerals are contained in the mixture Thus, before coal can be sold to consumers, it must be cleaned The cleaning process consists of a number of steps that results in a product that is specifically suited toCoal Washing | EncyclopediaClean coal is an energy that can generally be used as fuel, the fine coal of bituminous coal is generally used for coking The main reasons of washing coal are as bellow: 1 Improve coal quality and reduce emissions of coalfired pollutants Coal washing can remove 50%80% of ash and 30%40% of total sulfur (or 60%~80% of inorganic sulfur) in coalCoal washing | Coal preparation | Coal washing plant pcocess
