various uses of coking coal in aluminia industries

World Coal Association. Coking coal must also have low sulphur and phosphorous contents. Almost all metallurgical coal is used in coke ovens. The coking process consists of heating coking coal to around 1000-1100ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in a hard porous material - coke.
