How to Extract Iron from Hematite: Methods and Plants
It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.
