Technology for Recovery of Chromite Values from Tailings/Slimes Produced by Chromite Ore Beneficiation Plant

Accessibility Controls

Implementing Organization

National Metallurgical Laboratory (NML)

Project Overview

The technology exploits the difference in density of the chromite ore and the associated gangue minerals for their separation using fine gravity separator. The technology was developed at the bench scale and subsequently validated through pilot-scale trials. It produces marketable chromite concentrate with final tailings assaying < 10 % Cr2O3 meeting IBM guidelines for disposal of tailings.

Benefits

It has severaladvantages viz.
Additional resource generation, Creation of additional space for storage of tailings, Reduces potential damage to the environment, It's a waste recovery process that is environmentally friendly and techno-economically favorable.
