  • Coal steel

    Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then 'purified' or 'carbonised' in a series of coke ovens, known as batteries, where the coking coal is heated to ºC in the absence of oxygen for 1236 hours. During this process, byproducts are ...
