  • Metallurgical Coke - Oxbow

    Metallurgical coal is used in the production and purification of metallurgical coke. It is during the heating process that the unstable components are released. The final product is a non-melting, solid, stable carbon. However, the "ash" elements, which were part of the original bituminous coal, remain encapsulated in the resultant met coke.
