Edward M. Ripley, Chusi Li, in Processes and Ore Deposits of Ultramafic-Mafic Magmas through Space and Time, 2018 3.3.3 Chromite Deposits. Two models have emerged for the genesis of stratiform chromite deposits, but both relate in some form to concentration of chromite in magma chambers.
Jul 20, 2017 The average grade of the metallurgical chromite ore was 43.4 pct Cr2O3, with 52 pct of the ore having a chromium-to-iron ratio of 31 or over, 17.6 pct having a ratio between 21 and 31, and 30.4 pct having a ratio less than 21. Chemical-grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium-to-iron ratio of 1.51 to 21.
Chromite is an oxide mineral composed of chromium, iron, and oxygen FeCr 2 O 4 . It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or ...
Vol.8,No.5 Characterisation and Pre-concentration of Chromite 369A critical review on practice of the plant operating personnel is concerned in the grade-recovery characteristics of unit operations. But separation insight and influence of different operating and process parameters are essential to understand and control the process.
A process mineralogical study based on three texturally and mineralogically different chromite-bearing ore types at the Nkomati nickel mine was undertaken, with focus on chromite. Chromite is a by-product of the Ni-Cu-Co-PGE ore at Nkomati Nickel mine. These being the PCMZMG medium-grade Ni-Cu sulphide silicate ore with disseminated chromite, PCMZHG high-grade Ni-Cu sulphide silicate ore ...
UG-2 ore contains two dominant suites of mineralisation chromite and aluminium silicate-based mineralisation. The feed to Impalas UG-2 plant contains 22 - 24 Cr 2 O 3, or roughly 50 chromite. The aluminium silicate mineralisation includes primary magnesium alumino-silicates such as feldspars, pyroxenes and chlorite, and
The ore concentration is defined as the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore to extract the metals. In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are

The process of chromite ore mining can be divided into 2 areas 1. Feed preparation. 2. Concentration. The feed preparation stage involves the introduction of various physical separation equipment including crushers, screens and grinding mills. The principal function of this stage is size reduction in preparation for the concentration phase.
The kinetics of reduction of chromite ore plays an important role in controlling the productivity of the processes and quality of Ferro-chromium. A considerable amount of research has been carried out on the carbothermic reduction of chromite ore to elucidate the kinetics and mechanism of the reduction process.
