The Effect of Pre-Oxidation on the Reducibility of Chromite Using Hydrogen: A Preliminary Study

open access: yesMinerals, 2022
The majority of ferrochrome (FeCr) is produced through the carbothermic reduction of chromite ore. In recent years, FeCr producers have been pressured to curve carbon emissions, necessitating the exploration of alternative smelting methods.

CHROMITE-PLATINUM MINERALIZATION OF CLINOPYROXENITE-DUNITE MASSIF ZHELTAYA SOPKA, NORTH URAL [PDF]

open access: yesМинералогия, 2020
The paper presents the new data on platinum group minerals (PGM) and chromite from the Zheltaya Sopka massif, North Urals. Few chromite bodies along with specific composition of chromite indicate weak ore-forming processes developed in this massif ...

The formation of chromite chains and clusters in igneous rocks

open access: yesJournal of Petrology, 2022
Crystal clusters are common in both extrusive and plutonic rocks, but the mechanisms by which they form are not well-constrained. Following a consideration of the physics of nucleation, we outline the expected microstructural characteristics of ...

A-site deficient chromite with in situ Ni exsolution as a fuel electrode for solid oxide cells (SOCs)

open access: yesJournal of Materials Chemistry A, 2021
A-site deficient chromite La0.65Sr0.3Cr0.85Ni0.15O3−δ (L65SCrN) decorated by in situ Ni exsolution was implemented as fuel electrode on 5 cm × 5 cm reversible electrolyte-supported solid oxide cells (rSOCs).

Detrital chromite from Jack Hills, Western Australia: signatures of metamorphism and constraints on provenance

open access: yesJournal of Petrology, 2021
Detrital chromites are commonly reported within Archean metasedimentary rocks, but have thus far garnered little attention for use in provenance studies.

Application of geological methods for prospecting of podiform chromite deposits in the Khoy ophiolite zone, Northwestern Iran

open access: yesJournal of Economic Geology, 2019
Introduction Podiform chromite deposits are small magmatic chromite bodies formed in the lower section of an ophiolite complex. Podiform chromite mines have produced 57.4 percent of the world’s total chromite production.

Green synthesis, characterization, and photocatalytic activity of cobalt chromite spinel nanoparticles

open access: yesMaterials Research Express, 2020
Eriochrome Black T, an azo dye, was degraded under visible light irradiation using CoCr2O4 nanoparticles as a photocatalyst. In this study, CoCr2O4 cubic-spinel nanoparticles were synthesized via a novel and green sol-gel method.
