Coal processing is where raw coal from the mine is cleared using different physical processes, with or without any chemical reagents, to get a product which can be sold in the market or can be used for different purposes such as power generation. Once the coal has been mined it needs to be processed.

Metallurgical coal (also called "met" coal) is an important raw material used in the steelmaking process, although very small amounts of coal (relative to the amount used for electricity) are needed. The coal used to make steel is heated without air in an oven at temperatures of as much as 2,060°F (1,125°F), until most of its volatile matter is released.

The processing of raw coal has poor economic benefit due to low coal ratio and low yield (Zhang, 2012). At the end of the other processes, the total particle size of the coal is selected, and the process needs to be recycled and dehydrated for coal slurry. As a result, the sludge is dehydrated, while the calorific value is low (Sun and Shan, 2006).

Coal oil is made by heating cannel coal with a controlled amount of oxygen, a process called pyrolysis. Coal oil was used primarily as fuel for streetlights and other illumination. The widespread use of kerosene reduced the use of coal oil in the 20th century. Coking coal is used in largescale industrial processes.
