Environmental Impacts Of Chromite Mining

Chromite mining pollution, environmental impact,

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.
