chromite is an iron chromium oxide mineral and the only ore of chromium metal
What is Chromium? Definition from Corrosionpedia
Chromium is commercially extracted from the chromite ore, which is iron chromium oxide (FeCr2O4). Chromium metal has proven of high value due to its high corrosion resistance and hardness. Chromium is used in metallurgy to impart corrosion resistance and a shiny finish.
Industrial Minerals
Chromite is the commercial name for iron chromium oxide (FeCr 2 O 4), a mineral containing chromium (a transition metal with multiple oxidation states) and iron oxide. In its purest form, chromite comprises chromium (Cr 2 O 3 ) at 68% and iron oxide (FeO) at 32%.
Chromite vs Chrome What's the difference? | WikiDiff
Noun (wikipedia chromite) (mineral) A dark brown mineral species with the formula FeCr 2 O 4.; Any member of the chromitemagnesiochromite series that is a mixed oxide of iron, magnesium and chromium with the formula (Fe,Mg)Cr 2 O is a commercial source of chromium.
Chromite an overview | ScienceDirect Topics
Chromium metal is obtained commercially by heating chromite ore in the presence of carbon, aluminum, or silicon, and subsequent purification (ATSDR, 2000). Sodium chromate and dichromate are produced by roasting chromite ore with soda ash and are the primary chromium salts from which most other chromium compounds are derived (ATSDR, 2000).
