Precipitation and dissolution of chromite by hydrothermal ...

2014-1-1  Chromite is a typical refractory igneous mineral, precipitated from mafic magmas at relatively high temperatures. Chromites commonly occur in sedimentary, metamorphic, and metasomatic rocks, where they are interpreted as relics of an igneous phase and serve as the source of Cr for low-temperature Cr-bearing minerals. We present evidence for the nucleation of chromite within

Fusion of Chromite Ore Using Sodium Phosphate Salt as

2021-4-5  In hydrometallurgy, fusion techniques are considered key in the processing of chromite ore. Salts containing easily ionized elements are often used as flux, which results in solutions with complicated matrices. A matrix correction approach was developed to remove sodium and phosphate ions from a solution obtained from the fusion of chromite using sodium phosphate salt as flux. The

2020-9-24  Chromite mining activities are indispensable for production of goods and services. Sukinda is a major mining site of Odisha, India, polluted by chromium, which is highly toxic in its hexavalent form. The Sukinda valley is a rich source of chromites, amounting to almost 95% of Cr available in India, and is the fourth most polluted site worldwide. Immediate solutions are needed to protect the ...

Investigating the solid phase synthesis of lanthanum

We studied the kinetics of solid phase synthesis of lanthanum chromite and solid solutions based on it in the system La2O3-Cr2O3-CaO-O2.A relationship was obtained between the degree of conversion in the system and the synthesis temperature, the exposure time, and the CaO concentration. The synthesis of pure LaCrO3 from oxides is quantitatively complete at 1695 K and with an exposure time of 2 ...

2017-8-29  Naturally occurring Al- Fe3 +- poor magnesiochromite and Fe2+- Fe3 +- rich ferrian chromite solid solutions have been analyzed by micro-Raman spectroscopy. The results reflect a strong positive correlation between the Fe3 + # [Fe3+/(Fe3 ++Cr + Al)] and the positions of all Raman bands. A positive correlation of the Raman band positions with Mg# [Mg/(Mg + Fe2 +)] is less stringent. Raman ...

Chromite - an overview ScienceDirect Topics

Chromite (Cr) occurs exclusively in mafic and ultramafic igneous rocks (Papp and Lipin, 2006).Although some Cr-based minerals such as crocoite (PbCrO 4), vauquelinite (Pb 2 Cu[CrO 4][PO 4]), uvarovite (Ca 3 Cr 2 [SiO 4] 3), and merumite (4(Cr,Al) 2 O 3 3H 2 O) are well known, chromite (FeCr 2 O 4) is the only one that is a commercially recoverable source of Cr (Sueker, 2006; Glastonbury et ...
