magnetic separation for iron ore beneficiation. Concentration of iron ore with lowintensity magnetic separators has been used for decades in the recovery of magnetite while gravity separation and froth flotation are two important processes for mineral beneficiation, other methods can be used to concentrate minerals and separate them from gangue and each other
Magnetic Separators For Mineral ProcessBunting Redditch
Oct 22, 2021 · Magnetic separators can be found in most mineral processing operations, especially those processing non-metallic minerals and magnetic ores. This article investigates the use of high intensity magnetic separators and magnetic separation equipment in the minerals sector with a focus on processing dry materials (in the15mm, +45 micron size range).
The ore which can be attracted by the magnetic field can be concentrated by the process of magnetic separation. Among the ores mentioned in table 6.1, the ores of iron such as haematite (Fe 2 O 3), magnetite (Fe 3 O 4), siderite (FeCO 3), and iron pyrites (FeS 2) can be separated by the process of magnetic separation.
