For the production of ferrochromium the chromite ore (FeCr 2 O 4) is reduced with either aluminium or silicon in an aluminothermic reaction and for the production of pure chromium the iron has to be separated from the chromium in a two step roasting and leaching process.
In the past few decades, mining has generated more than 90 per cent of . of metallic mineral ores, notably of nickel, cobalt, chromium, iron, copper, lead, zinc, gold . At present, the mean concentration of mined nickel ore is about 2.6 per cent,.
There does not appear to be very much, if any, at Telluride, Colorado. Heating the telluride ore is sufficient to liberate the gold. Gold is frequently associated with silver, and the two metals are alloyed in the recovered metal. Unlike other metals, gold has not been acquired by mining until modern times.
Chromium: A Thoroughly Modern Metal Hidden in Plain Sight. Crocoite is unusual in appearance but rarely found. Beginning with the use of chrome plating in the art deco designs of the 1930s through its heyday in the cars, furniture and appliances of the 1950s and 1960s, chromium has been closely associated with the fast-paced modern world.

For the production of pure chromium, the iron has to be separated from the chromium in a two step roasting and leaching process. The chromite ore is heated with a mixture of calcium carbonate and sodium carbonate in the presence of air. The chromium is oxidized to the hexavalent form, while the iron forms the stable Fe 2 O 3.
