Environmental Risks of Mining

There are many environmental issues associated with nickel including greenhouse gas emissions, habitat destruction, and contamination of air, water, and soil. Nickel deposits are typically found in low-grade ores (~1-2% nickel) thus making it highly energy intensive to extract and refine the metal.

Environmental Impact Assessment Guidelines for the Mining ...

The refining of ore releases huge quantities of toxic gases into the atmosphere, and is a major contributor to acid rain. As a result, the environmental impact of our exploitation of mineral deposits can be severe. The amount of rock waste produced by mining activities is truly staggering, particularly when low-grade ores are recovered by ...
