Grinding: The raw ore enters the ball mill for grinding, and works together with the classifier to form a closed-circuit ring mill. Separation: After two stages of magnetic separators, iron ore and other magnetic impurity minerals are separated. The concentrate enters the dehydrator for dehydration, and the filter press presses the concentrate into a filter cake.

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.
