the recovery of iron as hematite

Processes for Beneficiation of Iron Ores – IspatGuru

WHIMS applications include recovery of iron from natural ore fines, upgrading of spiral concentrates, and recovery of hematite from tailings. In wet high intensity magnetic separations (WHIMS), electromagnets produce a very high-strength magnetic field that is applied to a matrix consisting of steel balls, spaced grooved plates, steel wool or pieces of expanded metal.

Economic Iron Bearing Minerals

For example, taconite is an iron ore that is mined extensively in USA, which contains the minerals hematite and magnetite, which in turn contain the iron. The terminology can become blurred as some ores that are mined are almost homogenous-therefore, in a situation in which an extracted ore is predominantly hematite, the term hematite will refer to both the iron ore and the iron bearing mineral.

Strengthening iron enrichment and dephosphorization of

Under these optimum conditions, iron concentrate with an iron grade of 59.74% and iron recovery rate of 86.31% were obtained by magnetic separation. However, as the ore particle size became finer, it becomes difficult to capture the fine particles by magnetic separation, which would reduce the recovery rate of iron ore [ 24 ]. Get price
