text: A process which comprises heating a charge mixture comprising lime and chrome ore containing ferrous chromite to produce a molten product comprising calcium chromite formed by substitution of calcium oxide for ferrous oxide of chromite, reducing ferrous oxide thereby displaced to produce a metallic iron product and a separable calcium chromite product, having a higher CrzFe ratio than the original ore, separating the metallic iron product and the calcium chromite product, and separately reducing the latter to ferrochromium.
