Chromium

Chromium is a chemical element which is denoted by the symbol Cr and its atomic number is 24. It is a steel-gray, radiant, hard metal that show cases a high polished surface and has a high end melting point. It is also odorless, bland, and pliable.

During the 1800s chromium metal was mainly utilized as a element of paints and in leather tanning salts but now metal combinations sum up for 85% of the usage of chromium. The remnants are used in the chemical manufacturing, refractory and foundry industrial sectors. Chromium was given the name such after the Greek word that spells "Chroma" that means color, for the reason of the many colorful compounds made from it.

Chromium is mined as chromite (FeCr2O4) ore. About 2/5ths of the chromite ores and concentrates in the world are fashioned in South Africa, while Kazakhstan, India, Russia, and Turkey are also sizeable producers. Unexploited chromite deposits are plentiful, but geographically resolute in Kazakhstan and southern Africa.

As chromium metal elements were utilized in dyes and paints and the tanning of leather, these elements are habitually recognized in soil and groundwater at discarded industrial venues, now requiring environmental cleanouts and remediation as per the dealing of Brownfield land. Primer paint comprising hexa-valent chromium is even currently used extensively for aerospace and automobile refinishing appliances.
