Chrome ore beneficiation challengesopportunities A
2011-4-1 Commercial chromite ore beneficiation processes. Pure chromium is difficult to produce since it is readily contaminated by many other elements. Huge quantity of raw chromite ore is being mined and beneficiated in various chrome ore beneficiation plants throughout the world to cater the customized needs of various ferro alloy plants.

Chromite mining pollution, environmental impact, toxicity
2020-9-24 Chromite mining activities are indispensable for production of goods and services. Sukinda is a major mining site of Odisha, India, polluted by chromium, which is highly toxic in its hexavalent form. The Sukinda valley is a rich source of chromites, amounting to almost 95% of Cr available in India, and is the fourth most polluted site worldwide. Immediate solutions are

Chromite: from the mineral to the commodity
2015-6-8 The most commonly used beneficiation methods for chromite ores are the gravity methods, such as the shaking table, jig, spiral and Reichert cone methods. The present work deals with the geologic studies that, coming after prospection, lead to the evaluation of the chromite ore quality and to planning and/or improvement of beneficiation plants.

(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.
