metcokeCoke is a gray solid carbonaceous product with porous structure and very high caloric content derived from coking coal.

Coke is used both as a source of energy and as a reducing agent in the production of pig iron. Because of its high and stable burning temperature, its high crushing strength and its properties as a chemical reducing agent, it is a key element in the production of Iron and Steel. 90% percent of all coke produced is used in this industry.
