Landsat-8 data for chromite prospecting in the Logar Massif, Afghanistan

Heliyon, 2018
Chromite is widely distributed in the east and southeast of Afghanistan, especially in Logar Province. Chromite mineralization is podiform-type and is hosted in the stratigraphically lowest ultramafic rocks of the Logar Ophiolite Complex.

Novel preparation of highly photocatalytically active copper chromite nanostructured material via a simple hydrothermal route. [PDF]

PLoS ONE, 2017
Highly photocatalytically active copper chromite nanostructured material were prepared via a novel simple hydrothermal reaction between [Cu(en)2(H2O)2]Cl2 and [Cr(en)3]Cl3.3H2O at low temperature, without adding any pH regulator or external capping agent.

Photocatalytic degradation and photo-Fenton oxidation of Congo red dye pollutants in water using natural chromite—response surface optimization

Applied Water Science, 2017
Refined natural Fe-chromite was characterized by XRD, FT-IR, reflected polarized microscope, XRF and UV spectrophotometer. Photocatalytic degradation and photo-Fenton oxidation of Congo red dye by Fe-chromite was investigated using 1 mL H2O2.

Attractive study of the antimicrobial, antiviral, and cytotoxic activity of novel synthesized silver chromite nanocomposites

BMC Chemistry, 2022
Antibiotic resistance is a global problem. This is the reason why scientists search for alternative treatments. In this regard, seven novel silver chromite nanocomposites were synthesized and assayed to evaluate their antimicrobial, antiviral, and ...

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

Minerals, 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.

A comparison of trace element concentrations in chromite from komatiites, picrites and layered intrusions: Implications for the formation of massive chromite layers.

Canadian journal of earth sciences (Print), 2022
By examining the minor and trace element contents of chromites from three intrusions; the Bushveld Complex (South Africa), the Stillwater Complex (USA) and the Great Dyke (Zimbabwe), and comparing these chromite compositions to those of magmas from which

Combustion and Pyrolysis EA-IRMS Techniques to Determine the δ²H of Diamonds. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

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

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