Chromite mining pollution, environmental impact, toxicity

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 needed to protect the health of biotic species of this region and their surroundings. Here we review chromite mining

The Environmental Impact of Mining (Different Mining

Mining remains an essential and growing part of the modern industry. By some estimates, it makes up nearly 45% of the total global economy, and mineral production continues to increase as demand for raw materials grows around the world.. However, many mining techniques still in use can have serious impacts on both the mining site itself and the surrounding environment.

What Is The Environmental Impact Of The Mining

Environmental Impacts Of Mining . As mentioned previously, mining activities can harm the environment in several ways. These are as follows: Air Pollution . Air quality is adversely affected by mining operations. Unrefined materials are released when mineral deposits are exposed on the surface through mining. Wind erosion and nearby vehicular traffic cause such materials to become airborne
