Magnetite concentrate grades are generally in excess of 70% iron by weight and usually are low phosphorus, low aluminium, low titanium and low silica and demand a premium price. Hematite. Due to the high density of hematite relative to associated silicate gangue, hematite beneficiation usually involves a combination of beneficiation techniques.

Magnetite was originally called lodestone but was formally named in 1845 for a locality in Magnesia, Greece. Note: Magnetite and hematite can appear very similar but are easily distinguished. Hematite has a rust red streak; magnetite has a black streak. In addition, magnetite will attract a magnet, while hematite will not. Limonite

There are many mineral processing methods, and there are two commonly used methods (1). Roasting magnetic separation Roasting magnetic separation is one of the effective methods to separate fine to fine (< 0.02mm) weakly magnetic iron ore.
