The steelmaking process starts with the processing of raw iron ore. The rocks that are mined containing iron ore are ground and the nearelemental iron is extracted using magnetic rollers. This fine iron ore is then processed into clumps that can be put inside of a blast furnace. At the same time, coal is cleaned of impurities in a furnace.
The Mining Process. ... To define the ore from the waste rock, ... Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
