Case Study: Chromite mining and health concerns 5 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, …
Chromite, Fe 2+ Cr 2 O 4, is the principal ore mineral of chromium in magmatic ore deposits and it can have a wide range of compositional variation because of multiple cationic substitutions that involve e.g. Ti, Mn, Mg, Al, Fe, Zn.However, substitution of Fe 3+ for Cr 3+ can occur to a larger extent which gives rise to iron-rich chromite …
Podiform chromitites in the mantle sections of ophiolites belong to either high-Cr (metallurgical) or high-Al (refractory) varieties. Their highly variable compositions are reflected by different Cr#s [100Cr / (Cr + Al)] and Cr 2 O 3 and Al 2 O 3 contents of the chromite, falling in the boninitic and MORB fields, respectively. Parental magmas of …
