Editing Chromite (section)

=== Reactions ===
Chromite is an important mineral in helping to determine the conditions that rocks form. It can have reactions with various gases such as [[Carbon monoxide|CO]] and [[Carbon dioxide|CO<sub>2</sub>]]. The reaction between these gases and the solid chromite grains results in the reduction of the chromite and allows for the formation of iron and chromium [[alloy]]s. There could also be a formation of metal [[carbide]]s from the interaction with chromite and the gases.<ref>{{Citation|last=Eric|first=Rauf Hurman|chapter=Production of Ferroalloys|date=2014|pages=477–532|publisher=Elsevier|language=en|doi=10.1016/b978-0-08-096988-6.00005-5|isbn=9780080969886|title=Treatise on Process Metallurgy}}</ref>

Chromite is seen to form early in the [[crystallization]] process. This allows for chromite to be resistant to the alteration effects of high temperatures and pressures seen in the [[Metamorphic rock|metamorphic]] series. It is able to progress through the [[Metamorphic rock|metamorphic]] series unaltered. Other minerals with a lower resistance are seen to alter in this series to minerals such as [[Serpentine subgroup|serpentine]], [[biotite]] and [[garnet]].<ref>{{Cite web|url=https://www.galleries.com/minerals/oxides/chromite/chromite.htm|title=CHROMITE (Iron Chromium Oxide)|website=www.galleries.com |url-status=live |archive-url=https://web.archive.org/web/20111017013049/https://www.galleries.com/minerals/oxides/chromite/chromite.htm |archive-date=October 17, 2011 |access-date=2019-03-17}}</ref>
