In magnetic separation, as the mass and the magnetic susceptibility of the particle are fixed, only the magnetic field intensity or gradient can be varied to change the magnetic force. This is why it is extremely important to create a magnetic field of high intensity and gradient for oxidized iron ores in order to achieve higher iron recovery.
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 the -15mm, +45 micron size range).
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
Oct 04, 2018· 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.
Commercial magnetic particle separation. One of the earliest works in magnetic capturing using bulk magnets was reported by Miltenyi in . In this work, a Magnetic Cell Sorter (MACS) from Miltenyi Biotec is used to separate cells labeled with magnetic particles from non-labeled cells.
