Iron Mining Process. From blasting to crushing to separation – more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nation’s steel. Blasting Taconite is a very hard rock. Using explosives, the taconite is blasted into small pieces. The iron ore is separated from the taconite using magnetism

Processing of the ore ranges from simple crushing and screening and separating various size fractions of the ore to the processes that beneficiate or upgrade the quality of the iron ore products. This is done by physical processes, which remove impurities by difference in particle density or size gravity or size separation.
