As magnetite ore has lower iron content it must be upgraded to make it suitable for steelmaking. Magnetite requires crushing, screening, grinding, magnetic separation, filtering and drying. The final product is a high iron grade magnetite concentrate (+65% Fe), with typically very low impurities. Further processing produces pellets, which can ...
