Chromium is chiefly obtained from the mineral chromite. Basic Chromium mines located in South Africa, Kazakhstan, India, Albania, and Turkey. South Africa is the largest producer of chromium with amounting to 17 million metric tons annual capacity.
Chromite concentrate, when combined with a reductant such as coal or coke and a high-temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron.
Chromium allows for the stainless steel to be much harder and tougher. In addition, it prevents corrosion on iron and steel surfaces due to high temperatures. Shredded chromite ore is used to produce stainless steel.
