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.

Magnetic Separation Method - 911 Metallurgist
Magnetic separation is a process used to separate materials from those that are less or nonmagnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as “Ferromagnetics”, those ...
