The Chromothermic Reduction of Chromite

Impurities other than iron in the chromite are com monly present and remain in the product. This is no problem for ferro-alloy use, but, if high-puritychromic oxide is desired, additional processesofphysical orchem ical separation need to be employed. For example, mag nesia and alumina may form several per cent of the chromite spinel crystals.
