potential toxic effects of chromium chromite mining and:Chromium processing preparation of the ore for use in various products Chromium Cr is a brilliant hard refractory metal that melts at 1857 °C 3375 °F and boils at 2672 °C 4842 °F In the pure state it is resistant to ordinary corrosion resulting in its application as an electroplated
Cr Ore (an oxide of chromium and iron) is reduced by coal and coke to form the ironchromium alloy. The heat for this reaction can come from several forms, but typically from the electric arc formed between the tips of the electrodes in the bottom of the furnace and the furnace hearth. This arc creates temperatures of about 2,800 °C (5,070 °F).
Chromium mining and processing In nature, chromium is found as chromite ore, composed of elemental iron, oxygen and chromium (FeOCr 2 O 3). 1,2 heavily in about a 700 m vicinity around the Countries with commercially significant chromite mines include Russia, South Africa, Zimbabwe, Turkey, the Philippines and Chromite ore is initially
Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated

Like mining, beneficiation (processing, crushing, separating, smelting, refining, etc.) for chromite depends on the characteristics of the ore deposit and on the mining methods used. For example, an operation extracting only highgrade ore may require only hand sorting and screening.
Chromite ore can be mined to produce chromite concentrate. It can also be crushed and processed. 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.
