The fundamentals of the smelting process rely on the reaction between the basic ingredient iron ore, and the transmuted ingredient coke derived from metallurgical coal. Coke is created by a coking process involving the heating of metallurgical coal to 1100 to 1400 °C in the absence of oxygen [ 8 ] which enables the removal of impurities leaving almost pure carbon through a liquefaction process.

International Journal of Metallurgical Engineering

Basic oxygen furnace slag (BOF slag) is an unavoidable by-product of steelmaking process of basic oxygen furnace. The main chemical constituents of BOF slag are CaO, FeO, Al 2 O 3 , SiO 2 and MgO. Due to its high metallic value (FeO: 16-20%) and lime content (CaO: 45-50%), it is possible to use in iron making and steelmaking process to replace lime and recover iron and CaO.

By Noah Beecher Kelk Metallurgical coal, also called metcoal or coking coal, is a type of coal that is used in the production of steel. It is of a higher purity than thermal coal which is used in energy generation. To make steel, metcoal is heated at around 1100 degrees C to remove water and other chemicals. This is done without the presence of oxygen. The result is a lump of near-pure carbon
