After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota's iron ore mining industry. To make these pellets, the hard taconite ore is blasted and then ground down with water to a fine powder. The fine iron rich particles, mostly of magnetite are extracted from the powder by use of magnetism.

THE PROCESSING OF TACONITE Taconite cannot be used in a blast furnace in its natural state. This fact, combined with the fact that the crude ore contains only about 25 per cent iron, has necessitated the location of processing plants in the mining area, rather than at the steel-mill centers. A huge investment of capital is required.
