Chromite is the most important chromium ore mineral. It forms a complete solid solution series with many other members of the group, eg. in the Chromite-Hercynite Series, Chromite-Spinel Series, Chromite-Magnetite Series and the Chromite-Magnesiochromite Series.It is the iron analogue of Zincochromite, Cochromite, Manganochromite and Magnesiochromite and the Cr analogue of Hercynite ...

The conductivities of strontium- and calcium-doped lanthanum chromite in air at 1273 K are shown in Fig. 1, Fig. 2, respectively.Although there is some scatter among the reported values, which could be due to variation in factors such as porosity, there is a general increase with increase in strontium content, and this trend is indicated by the solid line.

Jan 18, 2019· A fundamental problem in the genesis of all stratiform chromite deposits is how layers of massive to semi-massive chromite that are commonly up to 1 m thick (e.g., Bushveld [South Africa], Stillwater [Montana, USA]), less commonly up to 10 m thick (e.g., Inyala and Railway Block [Zimbabwe], Ipueira-Medrado [Brazil], Uitkomst [South Africa], Sukinda [India]), but in some cases up to 100 m …

Chromite ore with a small amount of coke is ground wet in a ball mill, after which the resulting slurry is de-watered. It is mixed with a binder before being fed into a rotating drum or disc pelletizer, where it forms balls. Pelletizing occurs due to the rolling motion of the pelletizer without the application of pressure. The fines adhere to ...

Chromite is found as orthocumulate lenses of chromitite in peridotite from the Earth's mantle.It also occurs in layered ultramafic intrusive rocks. In addition, it is found in metamorphic rocks such as some serpentinites. Ore deposits of chromite form as early magmatic differentiates. It is commonly associated with olivine, magnetite, serpentine, and corundum.

What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.

Chromite production has historically revved up in times of war, as it’s used to make hardened steels and in the interior of large gun barrels, said USGS chromium specialist John Papp.
