Magnetite
How is magnetite processed? 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.
