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.

In the recent past, iron ore resources from Brazil consisted of relatively high-grade iron ore, commonly processed via multi-stage crushing/screening, gravimetric concentration, magnetic separation, and reverse flotation. However, the high-grade iron ore reserves are in decline, resulting in the need to process the lower grade itabirite iron ores.
