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 2000F 1000C, 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.
