  • (Bio)leaching Behavior of Chromite Tailings

    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.
