Chromite - Wikipedia

Chromite is found as orthocumulate lenses of chromitite in peridotite from the Earth's mantle.It also occurs in layered ultramafic intrusive rocks. In addition, it is found in metamorphic rocks such as some serpentinites. Ore deposits of chromite form as early magmatic differentiates. It is commonly associated with olivine, magnetite, serpentine, and corundum.

Beneficiation of Low Grade Chromite Ores from Sukinda

Chromite ore beneficiation plants in Sukinda region treat selected rich ores (A-38% Cr203) with a view to producing concentrate of about 50% Cr203 as directly marketable grade for export and domestic industries. This has resulted rejection and piling of huge quantities of low and sub-grade ore (10-38% Cr203). Beneficiation is mostly limited to size reduction, desliming and classification. The ...

01/01/2020  In this study, a two-stage pyro-hydrometallurgical process was investigated to extract scandium from a laterite ore. The first stage of the process involves carbothermic reduction in which iron, nickel, and cobalt contents of the ore are reduced with carbon at 1400–1600 °C and separated as a metallic phase. This process is similar to the conventional smelting process for the production of ...
