  • Chromite Wikipedia

    Chromite ore can be mined to produce chromite concentrate. It can also be crushed and processed. Chromite concentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron.

  • Method of concentration of magnesia chromite ore

    SUBSTANCE: chromite ores are raw material for production of ferro-chromium of various grades, of metallic chromium, of dyes and refractory materials. The method of concentration of magnesia chromite ore includes crushing of ore, oxidising roasting, cooling, crumbling and magnetic separation with production of chromite iron concentrate and iron containing product. Crumbling is carried out till
