The iron ore processing industry produces usable concentrations of ironbearing material by removing nonferrous rock (gangue) from lowgrade ore. In the United States, predominant iron ore is taconite which is a hard, banded, lowgrade ore. Ninetynine percent of the crude iron ore produced in the United States is taconite.
