Abstract Chromium (Cr) is a versatile element used in numerous applications in the metallurgical, chemical, foundry sand, and refractory industries. Chromite (FeCr2O4) is the only commercially...
Chromite is a derived term of chrome. As nouns the difference between chromite and chrome is that chromite is (mineral) a dark brown mineral species with the formula fecr 2 o 4 while chrome is chromium, when used to plate other metals. As a verb chrome is to plate with chrome.
Chromite minerals are mainly found in mafic-ultramafic igneous intrusions and are also sometimes found in metamorphic rocks. The chromite minerals occur in layered formations that can be hundreds of kilometres long and a few meters thick. Chromite is also common in iron meteorites and form in association with silicates and troilite minerals.
Chromite is an oxide mineral belonging to the spinel group, a complex mineral containing magnesium, iron, aluminum, and Cr in varying proportions, depending on the deposit, that can be represented as FeCr 2 O 4 or (Fe 2+,Mg) [Cr,Al,Fe 3+] 2 O 4 (Murthy et al., 2011; Sanchez-Segado et al., 2015).
Chromium is mined as chromite (FeCr2O4) ore. About 2/5ths of the chromite ores and concentrates in the world are fashioned in South Africa, while Kazakhstan, India, Russia, and Turkey are also sizeable producers. Unexploited chromite deposits are plentiful, but …
Chromite Antigorite Comments: Chromite veins in yellow to green antigorite with picrolite, chromian antigorite and dolomite (polished section). Location: Wood's Mine, near 'Texas', Little Britain Township, Lancaster County, Pennsylvania, USA.
Chromite is a cumulate mineral which is found in ultramafic portions of layered mafic intrusions or in serpentines and other metamorphic rocks derived from the alteration of ultrabasic rocks. Due to its high crystallization temperature, this mineral is often found in the lower parts of magma bodies from the fractional crystallization process.
