Content Headlines of CD ROM
  • Chromium is a naturally occurring element found in rocks, animals, plants, soil, and in volcanic dust and gases.
  • Chromite deposits are mined by both underground and surface techniques.
  • Chromite is commonly found as brittle masses in peridotites, serpentines, and other basic igneous and metamorphic rocks. The principal producing areas are South Africa, Russia, Albania, the Philippines, Zimbabwe, Turkey, Brazil, India, and Finland.
  • The most common forms are chromium(0), chromium(III), and chromium(VI). No taste or odor is associated with chromium compounds.
  • The economics of chromite ore recovery depend on the occurrence of the mineral and its chemical composition.
  • Chromium-bearing pigments include both trivalent and hexavalent chromium compounds.
  • Chromium(III) is an essential nutrient that helps the body use sugar, protein, and fat.
  • Breathing high levels of chromium(VI) can cause irritation to the nose, such as runny nose, nosebleeds, and ulcers and holes in the nasal septum.
  • Chromium is a constituent of a variety of alloy steels, cast iron, and, non- ferrous alloys, chromiumís function in these products is to enhance their mechanical properties or to impart
    special properties of electrical or abrasive resistance.
  • In the metallurgical industry, chromite ore is blended with carbon-rich material and with fluxes (material that promotes fusing of metals and otherwise aids physical and chemical processing), fed into an electric-arc furnace, and smelted.
  • Before plating, most metal surfaces are cleaned in a degreaser, conditioned for the plating process in a series of acid and caustic baths and then rinsed to remove remaining bath liquids.
  • The chemical industry feeds dried, crushed, and ground chromite ore mixed with soda ash (a source of sodium carbonate) into a rotary kiln furnace.
  • The refractory industry crushes chromite ore and blends it with magnesia to make shaped and unshaped refractory products. Shaped refractories are bricks that are assembled where they are used such as in a furnace.
  • Chromium in stainless steel is recycled when stainless steel is reused.
  • Crushing of lumpy Chrome ore requires Jaw Crushers, Drum Roller Crushers and Hammer Crushers.
  • The purpose of beneficiation is to render the ore physically and chemically suitable for further treatment.
  • The total cost of beneficiation plant project is Rs. 8.86 millions. This amount includes the land, machinery,building, furniture and fixture, and raw material inventory etc. However, the cost of land varies from area to area.
  • Chromium contained in
    chromite ore and chromium ferroalloys and metal were imported from South Africa(37%), Turkey (13%), Russia (18%), Kazakstan (8%),Zimbabwe (7%), and other nations totaling 22%.
  • In several large applications, users have implemented plans that will result in replacement of 20 percent of hard chrome with thermal spray within two to three years, and up to 80 percent replacement by 2010 or shortly thereafter. While hard chrome markets are stable in the near term, by the end of the decade, serious erosion in those markets can be expected.
  • Some 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Chemical and metallurgical industries use about 85% of the chromite consumed in the United States.
  • Major producers are South Africa, Philippines, India, Kazakhstan, Turkey, Pakistan, UAE and Oman.
