B.C. researchers develop new coal ‘washing’ process JWN

Aug 17, 2020· Metallurgical coal is still black after it’s been washed, but it is considered “cleaner” because the washing removes ash and certain minerals. The washing is needed in order to test the coal for its quality. But the conventional cleaning methods use toxic chemicals that are carcinogenic.

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
