Chromite: The only mineral ore of chromium metal
Chromite is important because it is the only economic ore of chromium, an essential element for a wide variety of metal, chemical, and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium.

Chrome Ore Beneficiation Process | Chromite …
The chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral. The dissociation degree of ferrochromium ore is low, and it has a weak magnetic property. First of all, magnetic separation processing to separate chromite. Besides, the stone size is fine, so there is no need for grinding, the grading result shown in the below.
Method of concentration of magnesia chromite ore
The method of concentration of magnesia chromite ore includes crushing of ore, oxidising roasting, cooling, crumbling and magnetic separation with production of chromite iron concentrate and iron containing product. Crumbling is carried out till obtaining fractions of not more than 80 mm. Roasting is performed in oxidising medium within temperature range of 900°-1000°C; conditioning is ...

CHROMITE (Iron Chromium Oxide) - Amethyst …
Chromite is the most important ore of chromium from which it derives its name. Chromium is an important metal and has a wide range of industrial uses. Chromite forms in deep ultra-mafic magmas and is one of the first minerals to crystallize. It is because of this fact that chromite is found in some concentrated ore bodies. While the magma is slowly cooling inside the Earths crust, chromite ...

Magnetic Separation and Iron Ore Beneficiation – …
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.
Chromite Ore - an overview | ScienceDirect Topics
Chromite ore has a spinel structure with a general formula of (Fe,Mg)O.(Cr,Al,Fe) 2 O 3.The content of Cr 2 O 3 for metallurgical-grade chromite ore is in the range 42–55% and the chromium-to-iron ratio is higher than 1.5. These quantities determine the chromium content in the smelted chromium ferroalloys. Magnesium oxide and alumina are refractory at the smelting temperature and fluxed with ...
