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.
Many researchers focus on the dephosphorization of high phosphoruscontaining oolitic hematite ore by adding a large amount of additive during the reduction process [27,28]. For example, reduced iron with <% phosphorus was obtained by magnetic separation following the coalbased reduction of an oolitic hematite ore containing % phosphorus
