Iron Ore Processing
The process is simplified. The roasted ore is subject to magnetic separation after water quenching and classification. After magnetic separation, the magnetite fine powder with high iron grade, low arsenic and sulfur impurities is obtained. It is widely used for beneficiation of ores and waste residues containing weakly magnetic iron minerals.

Iron Ore Processing, General
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.
