WebMaking Iron. The iron used for making steel commonly consists of three main presentations. Raw ore- a compound found in nature containing iron, oxygen, and other minerals. Pellets- iron ore that has been crushed and the unwanted compounds removed to create a concentrated iron powder which is further processed to make pellets. WebMetallurgical (met) coal (or coking coal) is a naturally occurring sedimentary rock found within the earth’s crust. Categories of met coal include hard coking coal, semi-hard coking-coal, semi-soft coking coal and pulverised coal for injection (PCI). These apply to the different quality grades of met coal, all of which are used to make steel.
