Mining and Quarrying - FIRST for Sustainability

Open-pit mines are often not re-vegetated after exploitation and therefore are exposed to wind and weather which leads to erosion. Mining operations sometimes require a lowering of the groundwater level or a drainage of the mining site, thus making water unavailable for other users and the environment. • Leaking containment ponds are the main disaster risk within the mining industry.

In mining and quarrying, water is used and gets polluted in a range of activities, including mineral processing, dust suppression, and slurry transport. In addition, water is subtracted from the environment in the process of dewatering, the process of pumping away the water that naturally flows into the pit or tunnels of the mine. When disposed, this water may also carry pollutants. The mining ...
