Chromium processing - Chromium processing - The metal and its alloys: By far the greatest use of chromium is as a ferrochromium alloying agent in steel manufacture. Pure chromium is added to nonferrous alloys and is also applied as a corrosion-resistant surfacing for other metals. Chromium surfaces are produced on other metals by electroplating and chromizing.

Chromium is a naturally occurring element found in rocks, animals, plants, soil, and in volcanic dust and gases. Chromium is present in the environment in several different forms. The most common forms are chromium 0 , trivalent or chromium III , and hexavalent or chromium VI . Chromium III is an
Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6.It is a steely-grey, lustrous, hard and brittle transition metal. Chromium is the main additive in stainless steel, to which it adds anti-corrosive properties.Chromium is also highly valued as a metal that is able to be highly polished while resisting tarnishing.
From the early 1900s to 1954, a company called the Mutual Chemical Company operated a "chrome ore" processing plant across the street from 441 Route 440, where the Seven Trust is now lo ed. The plant produced chromium products that were used as a key ingredient in stainless steel and in heating and cooling systems. Approximately 40% of the
Chromium Cr is considered as one of the chronic pollutants that cause damage to all living forms, including plants. Various industries release an excessive amount of Cr into the environment. The increasing accumulation of Cr in agricultural land causes a significant decrease in the yield and quality of economically important crops.

The Chromium Cr content in initial soil was quite high. The source of soil contamination by heavy metal may be as a result of top dressd-soil, which was collected from Hazaribag beri- badh, near the bank of river Buriganga a highly industrial ef- fluents polluted area. There is no doubt that heavy metals are also present in soil naturally and non-degradable.
Solid wastes from chromium-processing facilities, when used as fill material, have generated chromium point source contamination of soils and groundwaters, that remains after decades in many urban and peri urban areas all over the world, causing environmental impacts that need to be addressed in a sustainable economic, social and environmental way.
