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 …

the total reserves/resources of chromite in the country as on 1.4.2015 has been estimated at 344 million tonnes with 102 million tonnes as "Reserves" (30%) and 242 million tonnes as "Remaining Resources" (70%). More than 96% resources of chromite are located in Odisha, mostly in Jajpur, Kendujhar and Dhenkanal districts. Minor deposits
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]), …
For both chromite deposits, the forsterite (Fo) contents of olivine increase from harzburgite (90.0–91.6) to dunite (89.9–94.6) and chromitite (90.0–97.2). Mineral compositions of olivine show significant variabilities at the contact boundaries between densely disseminated and sparsely disseminated chromitites. These features suggest that ...
Chromite from podiform deposits may have distinctly lower Cr-numbers and thus higher Al and ... within the Nigerian Basement Complex has been reported (Wright and Ogezi, 1977; Onyeagocha, 1979; ...
In Orissa, India, chromite deposits occur in a NE-SW trending belt as discontinuous pods associated with tectonically deformed and metamorphosed ultramafic rocks. Geological mapping and detailed geophysical survey (including gravity, magnetic, electrical, and electromagnetic methods) for exploring chromite were conducted in a area at Tangarparha, located within the …

The massive chromite deposit in the Ring of Fire follows a 12 km strike-length. Each mining company seems to have a portion of this deposit, which remains to be fully explored. In the world of chromite mining, the Ring of Fire, if developed in …
Some known deposits were confirmed while new ones were identified and documented. The metallic minerals found in Nigeria include iron ore (with over 3 billion metric tonnes), ferro-alloy …
Currently, Africa is a world leader in the production of several high-value metals including gold, platinum, chromite, uranium, manganese, vanadium, tantalum and cobalt and industrial minerals phosphate, zirconium, vermiculite and gemstones. it is estimated that Africa is the repository of about 75% of the planet's total resources that remain ...
The geophysical signature of chromite deposits depends upon the physical properties of chromite ore (for example density, magnetic susceptibility, and resistivity). The density of chromite mineral varies from 4430 to 5090 kg/m3 (Deer et al., 1962) while that of mafic/ ultramafic rocks ranges between 3000–3600 kg/m3.
Other occurrences had been reported at Hamissanasol Hamed in the northern Red Sea Hills, the Nuba Mountains in southern Kordofan, JabalRahib northwest Sudan and Jabal El Tawil in central Butana. However, the Ingassana chromite …
(ii) Copper-cobalt-uranium mineralization in Late CONCLUSION The Nigerian basement complex is marked by a rela- tive absence of large scale and significant metallic deposits though there are a variety of mineral occur- rences that are of types comparable with mineral deposits in other basement terrains, e.g. iron, gold, chromite and manganese.
Heroshah chromite deposits are part of Skhakot-Qila ultramafic complex associated with ophiolitic sequence in the vicinity of Main Mantle Thrust Zone (MMTZ) in NW Pakistan. The Heroshah chromite deposits are being mined regularly for chromite ore for the last five years at a rate of 70 to 80 tones per day.

In the aspect of ophiolite-type chromitite prospecting, a lot of research has been conducted by scholars. Li and Li (1993) applied the four-dimensional dynamic metallogenic theory to study the Luobusa chromite deposit in Tibet, and the relationship between different levels of tectonism and mineralization is explored. Wang et al. (2010) found that the occurrence of …
