The mined coal contains a mixture of different size fractions, together with unwanted impurities such as rock and dirt. Coal preparation (beneficiation) is the stage in coal production when the mined coal is processed into a range of clean, graded, and uniform coal products that are suitable for the commercial market.

Coal-tar pitch is the residue that remains after the distillation of coal tar. Coal tar and coal-tar pitch are used in coal-tar-based sealcoat products, although use of coal-tar pitch is more common than use of coal tar. Both coal tar and coal-tar pitch are known human carcinogens. Learn more about coal-tar-based sealcoat here.

First, the coal goes to a preparation plant where it is washed or cleaned to remove contaminants. The cleaning removes impurities like rock, ash, sulfur and other substances. A high amount of rock and clay particles reduces the quality and heating value of coal and usually means a lower price for coal. Some coal is crushed and mixed with water ...
