    Feb 03, 2019 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

    Nov 04, 2019 An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth they are then refined often by smelting in order to extract the valuable elements.
