Metallurgical coals fall broadly into two types (Figure 1). Coking coal is heated in the absence of oxygen in a coke oven to produce coke, which is then charged into blast furnaces as the key fuel and reactant. Coking coal can be further divided into hard coking coal (HCC), semihard coking coal (SHCC) and semisoft coking coal (SSCC).
