Chromiteorecan be mined to producechromiteconcentrate. It can also be crushed and processed.Chromiteconcentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron.

3.1 Chrome magnetic separationprocess. The chrome raworeis a flotation tailore, which is mainly formed in thechromite, and thechromiteis the target recovering mineral. The dissociation degree of ferrochromiumoreis low, and it has a weak magnetic property. First of all, magnetic separation processing to separatechromite.

Chromium processing, preparation of theorefor use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated

Theprocessofchromiteoreminingcan be divided into 2 areas: 1. Feed preparation. 2. Concentration. The feed preparation stage involves the introduction of various physical separation equipment including crushers, screens and grinding mills. The principal function of this stage is size reduction in preparation for the concentration phase.

Residues fromminingandchromiteprocessing are often toxic, not only because of the presence of hexavalent Cr (Cr(VI)) but because of the reagents and other waste materials in overburden and wastes.

Case Study:Chromiteminingand health concerns 5 Chromiumminingand processing In nature, chromium is found aschromiteore, composed of elemental iron, oxygen and chromium (FeOCr 2 O 3). 1,2 heavily in about a 700 m vicinity around the Countries with commercially significantchromitemines include Russia, South Africa, Zimbabwe, Turkey, the

Chromiteorehas 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-gradechromiteoreis 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.
