Taconite Ore Mining Process

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.
