Environmental Risks of Mining

Wastewater from these processes can pollute water sources nearby and deplete freshwater supplies in the region surrounding the mine. Some mines, such as the Mountain Pass mine in southern California, have implemented waste-water recycling technologies, resulting in a huge decrease in water demands and liquid waste (Molycorp, 2012). Case Studies
