Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using charcoal.

Grindability refers to the ease of pulverizing a coal sample compared to certain reference coals. The standard method of coal grindability is called Hardgrove (ASTM D409), though this method does not provide reproducible and repeatable results for hard coal. Another method that can be accepted for petroleum coke is the test method ASTM D5003.

In coal or coke grinding, screening and handling, the fine coal particles produce a dust sedimentation by the mechanical action in a local area, if particle leaks are not eliminated in the operations. Coke oven plants may suffer the worst local dust pollution out of coal processing.
Coal is ground to the size of a fine grain, mixed with air, and burned in the flue gas flow. Biomass and other materials, like waste, can also be added to the mixture. Coal contains mineral matter that is converted to ash during combustion. The ash is removed as bottom ash and fly ash. The bottom ash is removed at the furnace bottom.
