Coal Basics - Coal Marketing International

Metallurgical Coal. Coking coals are primarily used to make coke which under high temperatures reduces metal oxides to metals. This process occurs when the coke is combined with the metal oxides at elevated temperatures. The carbon from the coke combines with the oxygen from the metal oxides to produce carbon dioxide, liquid metal and residual ash (slag).
