Magnetic separationis 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.

Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral not only because it ismagnetic.The formula could be written as Fe 2 + Fe 3 + 2 O 4, which more precisely designates one of its peculiarities.It contains both ferrous (Fe 2 +) and ferric (Fe 3 +) ions, implying synthesis, growth, and stability within an environment where oxidized and reduced states ofironare present and maintained.

Ironprocessing -Ironprocessing - Ores:Ironores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributediron-bearing minerals are oxides, andironores consist mainly of hematite (Fe2O3), which is ...
A study of silica and iron recovery from the iron ore concentration tailing is presented.the residue is composed of 40.1% fe, 33.4% sio2, 8.31% al2o3, 0.08% p, and 0.34% mno.the developed process ofsilica and iron recovery consisted of size classification,magnetic separation, andremoval of impurities by leaching.
May 20, 2020·Magnetite iron oreprocessing flowsheet--wetmagneticseparationprocess. 1Iron oreis sent into the jaw crusher for primary crushing and then sent into the vibrating screen for screening, and the mesh size is controlled in the range of 35 mm to 75 mm. The materials on the screen are sent into the crusher for medium crushing and then sent into ...
Magnetiteprocessing also utilizes deslime thickeners for hydraulicconcentrationprior tomagneticfinishing and flotation of silica as the final concentrating step. Concentrating Hematite When processing hematite, Tilden must use a flotation system specially developed for the mine’s fine-grainedore, rather than bymagneticseparation.
Mineral processing - Mineral processing -Concentration:Concentrationinvolves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation),magnetic...
