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.It can be leached away from the waste material and then reduced and precipitated as chromic oxide (Cr 2 O 3).
In future it is planed to enlarge the production range of the plant by implementing production of different ferro-alloys, chromium oxide and aluminium powder. LLC "NSplav" is a reliable partner, performing his liabilities at a high quality and in due time.
