Magnetic Separation and Iron Ore Beneficiation IspatGuru

2018-10-4  Magnetic Separation and Iron Ore Beneficiation. Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.

Beneficiation of an iron ore fines by magnetization

These iron ores contain many detrimental impurities and are difficult to upgrade to make suitable concentrates for the blast furnace. In this paper, the beneficiation of a low-grade hematite ore fines containing carbonates with magnetization roasting and magnetic separation was proposed and studied.

Beneficiation of Iron with Magnetic Separators

Research on beneficiation of iron from iron-polymetallic was conducted according to the properties of the ore. The separation results show that magnetic separation is the best way to concentrate the iron mineral. The results show that iron concentrate assaying 60.15% Fe can be obtained with the recovery of 76.48%.
