Chromite Ore - an overview ScienceDirect Topics
Because chrome is a very hard metal and has a low coefficient of friction, chrome plating was also used for extending the life of parts that receive heavy wear, such as automobile cylinders, and was useful in boiler pipes to prevent build-up of scale (mineral deposits). Refractory materials are highly resistant to heat and are chemically stable. These materials are used as insulation

Chromium - Minerals Education Coalition
The only ore of chromium is the mineral chromite and 99 percent of the world’s chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years. It is mostly used for making stainless steel and other metal alloys.

PRODUCTION, CHARACTERISTICS AND USE OF
Chrome and iron oxides are reduced into metal in the submerged electrical arc furnaces by using metallur-gical coke. Simultaneously part of silica is also reduced. Produced metal is classified as “charge chrome” quality, which includes 53 % Cr, 7 % C and 4-5 % Si. Typical reduction reactions in the ferrochrome furnace can be seen in Figure 2.
