Conventional magnetic separation devices are widely used for the removal of tramp iron from a variety of feed materials and for the beneficiation of ferrous ores. These devices for separation of strongly magnetic materials employ a variety of mechanical designs.

 — Using this device to sort raw ore with a magnetic iron content of 3% and particle size of < 3 mm can result in a good index of 11.40% concentrate grade, 0.7% tailing grade, and 80.29% recovery.

Magnetic separation is used to enrich iron ore samples that demonstrate either para- or ferromagnetic behavior (Flippov et al. 2014). Magnetic separation can be performed on wet or dry material, with wet being a slurry (Flippov et al. 2014). Magnetic separators are broken down into two categories: high and low intensity (Flippov et al. 2014). Low

 — This chapter introduces the principle of how low-grade iron ores are upgraded to high quality iron ore concentrates by magnetic separation.

MRB = magnetic separator with channel and belt. Compact, interface-free system with proven individual components. High belt speed for loosened material and reliable extraction of impurities. High yield of ferrous metals. Working widths: 1,000 mm, 1,500 mm, 2,000 mm.

 — This chapter introduces the principle of how low-grade iron ores are upgraded to high quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth and can be readily extracted by low-intensity magnetic separators from magnetite ores. On the other hand, oxidized iron …

Magnetic separation is the most commonly used beneficiation method for ferrous metal ore such as iron ore. It is divided into weak magnetic separation and strong magnetic separation according to the different magnetic field strengths.

Magnetic separation of iron ores is one of the fastest-growing segments of the minerah beneficiation industry. The tonnage of taconite ores processed annually by magnetic separation toill, in a few years, reach 100 million.

 — The SLon-1000 magnetic separator can treat weakly magnetic minerals in the size range of 0–2.0 mm, and has been used in industry for upgrading roasted kaolin of 0–0.2 mm particle size by removing the impurities comprising oxidized iron ore and other weakly magnetic minerals.

 — The technologies applicable to beneficiating iron ore fines include wet and dry gravity and magnetic separation, flotation, and roasting followed by magnetic separation.
