2021-1-23 Odisha state is the major reserve of the chromite ore. Due to the extensive applications, high-grade chromite ore is getting depleted day by day. Now it is a challenge for the industry to utilize these low-grade ores and tailings. Several attempts were taken to upgrade the low-grade chrome ores and tailings using different gravity separation methods, magnetic separation methods, flotation, etc.

Chromite beneficiation operations in Sukinda valley (India) produce large amounts of tailings, which are stored in open air. In this study, bioleaching experiments were carried out in batch reactors with Acidithiobacillus thiooxidans or Pseudomonas putida in order to determine the potential leachability of metals contained in these tailings due to biological activity.

Large tonnages of chromite tailing were discarded during processing of chromite ore in the conventional circuit. A typical chromite plant tailing was treated in wilfley table for the recovery of chromite values. Optimisation study was carried out for the process parameters of wilfley table using empirical models, developed from the experimental data.
Read MoreThe samples of chromite tailing used in this work present 8.41% of Cr 2 O 3. This material is composed mainly chromite (specific gravity: 4.50 - 5.09), serpentine (specific gravity:2.53 - 2.65) and talc (specific gravity:2.7 - 2.8). It has been found that 48% of the tailings particles are less than 300 µm.
