Mar 01, 2021 Global Chrome Ore Market Overview. Chrome ore is a natural mineral formation containing chromium in such compounds and concentration as to make its commercial exploitation technically feasible and economically suitable. The metallurgical industry uses chromite ore (also known as chrome ore) to produce chromium ferroalloys and metal.
Chrome ore contains too many impurities to be added directly into a steelmaking furnace. Prior to being consumed in steelmaking, chrome ore must be smelted in an electric furnace together with a carbon reductant, which eliminates most of the impurities in the ore and produces a product known as ferrochrome. Ferrochrome is an alloy containing 48.
