The beneficiation of -200 µm iron ore will become more important as lower grade resources will require liberation of the contained iron ore at finer sizes. Currently, the treatment of -200 µm haematite-based iron ore is predominantly via flotation, specifically in Brazil and the USA. For -200 µm magnetite-based iron ore, treatment is ...
