Trace Elements in Chromite as Indicators of the Origin of the Giant Podiform Chromite Deposit at Kempirsai, Kazakhstan

Economic Geology, 2022
This study presents a complete trace element data set of chromite from the world’s largest podiform chromite deposit at Kempirsai, Kazakhstan, together with platinum group element (PGE) and Re-Os isotope compositions, to explore the potential of trace ...

Different Pathways for Cr(III) Oxidation: Implications for Cr(VI) Reoccurrence in Reduced Chromite Ore Processing Residue.

Environmental Science and Technology, 2020
Hexavalent chromium contamination is a global environmental issue and usually reoccurs in alkaline reduced chromite ore processing residues (rCOPR). The oxidation of Cr(III) solids in rCOPR is one possible cause but as yet little studied.

Spatial Association Between Platinum Minerals and Magmatic Sulfides Imaged with the Maia Mapper and Implications for the Origin of the Chromite-Sulfide-PGE Association

, 2021
The spatial association between Pt minerals, magmatic sulfides, and chromite has been investigated using microbeam X-ray fluorescence (XRF) element mapping and the Maia Mapper. This lab-based instrument combines the Maia parallel energy dispersive (ESD)

Chromite‐bearing quartzite in the southern fringe of Singhbhum Craton around Ghutrigaon, Eastern India: Petrogenetic implication

Geological Journal, 2021
The chromite mineralization in the southern fringe of the Singhbhum Craton around Ghutrigaon, Dhenkanal district, Odisha, Eastern India shows a unique nature of occurrence. The structural features, mineral assemblage, and spinel composition are different

Petrogenetic insights from chromite in ultramafic cumulates of the Xiarihamu intrusion, northern Tibet Plateau, China

American Mineralogist, 2020
Chromite is one of the earliest crystallized minerals from mafic melts and has been used as an important “petrogenetic indicator.” Its composition may be modified by interaction with intercumulate melt and adjacent minerals.

Selective shear flocculation of chromite from chromite-serpentine mixtures

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1998
Abstract In this study, shear flocculation of chromite from mixtures of chromite and serpentine was investigated. The effects of zeta potential, contact angle, stirrer speed, flocculation (stirring) time, settling time and concentration of sodium oleate, Na 2 SiO 3 and Na 2 SiF 6 were tested.

Magnesite-chromite products from high purity magnesite and chromite

Refractories, 1971
Products made from magnesite and chromite with low-impurity oxide concentrations possess better thermal factors than ordinary periclase-spinel refractories: refractoriness under load: 1700°C and above; bending strength at 1300°C 2.5–3 times greater; deformation 3–4 times; and the rate of deformation at steady-state creep is about a half.
