The chromites and associated platinum-group minerals (PGMs) crystallize from mafic-ultramafic magmas in a wide range of tectonic settings, e.g., stratiform/layered magmatic complexes, podiform complexes in ophiolites, Alaskan zoned complexes, and chromite-rich Archean complexes, also known as "conduit-type" [1–11].As the chromite composition …
The low-grade siliceous chromite ore from Ghutrigaon, Odisha, India, containing ~ 16% Cr2O3, with Cr/Fe ratio of 1.97 and ~ 55% of SiO2, does not find any use in metallurgical industry and hence considered as waste. Mineralogical investigation indicates the presence of chromite and quartz as major minerals with minor fuchsite and kaolinite. The …
