Coal is South Africa's major primary energy source, and plays a significant role in supplying the chemicals and steelmaking industries. The benefits of coal production are relevant in the light of South Africa's development priorities of job creation and economic growth. Even so, primary metal production and coal-based power generation industries, through their …
Mining, whether for fossil fuels or metals used in clean energy technologies, has serious environmental impacts, and it's hard to make apples-to-apples …
The long-term and continuous mining of coal deteriorates the natural environment as it sheds negative influences on the nearby water bodies and soil. 10 However, the regular disposal of millions of wastewater into the nearby water bodies is the main cause of pollution of water. 25 More specifically, the release of chemical particles …
Waste dumps generated from mining that exposes sulfur-bearing overburden can be active sources of acid generation with the potential to severely contaminate soils, surface and groundwater, and endanger both local and downstream ecosystems. A waste rock management strategy ensure that disposal of such material is …
