Chromite Ore Mining Methods 1

FIELD: mining. 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

However, chromite deposits that are large enough for mining are generally found in: 1) stratiform deposits (large masses of igneous rock such as norite or peridotite that slowly crystallized from subsurface magma); 2) podiform deposits (serpentines and other metamorphic rocks derived from the

    Chromite deposits are mined by both underground and surface techniques. Much of the ore is rich enough to be used directly: for production of ferrochromium, a rich, lumpy ore containing more than 46 percent Cr 2 O 3 and having a chromium-iron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3
