Developments in chemical separation of iron ore ...

01/01/2015  Chemical separation techniques for removing impurities from iron ores include caustic or acid leaching under a range of conditions. The leaching is usually preceded by a treatment to concentrate the impurity elements in the ore into a magnetic concentrate or to heat the ore to make the impurities more accessible to the leachant and so enhance their removal.

01/01/2015  The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.

Mineral processing - Wikipedia

The first pair of electromagnets was weakly magnetised and served to draw off any iron ore present. The second pair were strongly magnetised and attracted the wolframite, which is weakly magnetic. These machines were capable of treating 10 tons of ore a day. This process of separating magnetic substances from the non-magnetic substances in a mixture with the help of a magnet is called magnetic separation..
