Magnetite

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 be used directly in a blast furnace or steel-making plant. Where is magnetite exported to?
