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.

The Problem with Chromite ProcessingThe Chromite Extraction FlowsheetChromite Process Summary Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding.

Chromite is a mineral that is an iron chromium oxide. It has a chemical formula of FeCr2O4. It is an oxide mineral belonging to the spinel group. The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr2O4).[5] A substitution of the element aluminium can also occur, leading to

The processes adopted for beneficiating the chromite ores are mainly gravity and magnetic separation methods. With conventional methods depending on the liberation of particle size of the ore, significant amount of fine chromites are lost to the tailings (iek et

Chromite concentrate after grinding is subjected to two-stage magnetic separation with getting chromite and iron concentrates. However, this method is complicated, and the division of natural-doped iron ore is not possible to change the ratio Cr 2 About 3 /FeO in grains of chromite.
