Production. Aluminothermic production of high purity chromium metal accounts for over 95% of chromium metal produced today. The first step in this process requires that the chromite ore is roasted with soda and lime in the air at 2000 ° F (1000 ° C), which creates a sodium chromate containing calcine.
deposits of chromite occur in South Africa and Zimbabwe, with significant deposits in several other countries such as Finland,,250tonsofchromitewasproduced inNorthAmericaduring2012,%of the more than million tons of chromite produced internationally (ICDA, 2013).
Chromite deposits constitute the only primary source of chromium metal; in addition they record a remarkable phenomenon in the overall process of concentration by magmatic crystallization. Extensive literature exists on both aspects of chromite deposits.

production of lowcarbon ferrochromium. The most widely used technique at present time is the silicothermic process. Although much work has been carried out to study, improve and develop the silicothermic process, it is characterized by technical complications and relatively high contents of carbon in the ferrochromium produced (≈ % C)[1].

Process Selection. The key to process selection is to balance the costs, efficiency, output and quality of each option to meet your production goals. Some options may produce a higher output per hour while costing twice as much as other options, for example, while other options are .
It is relatively cheap and easy to extract a portion of the chromite from a platinum concentrator tailings stream at a grade of between 40–42% Cr2O3. However, it is only in recent years that some ferrochrome producers have begun to source some of their chromite from the tailings of platinum producers.
