Then the circulating load ratio equals

The iron ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. In the United States, predominant iron ore is taconite which is a hard, banded, low-grade ore. Ninety-nine percent of the crude iron ore produced in the United States is taconite.
