Coal Washing Encyclopedia

Coal 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 to

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 that
