CORE CASE STUDY Environmental Effects of Gold Mining

CORE CASE STUDY In Australia and North America, a mining technology called cyanide heap leaching is used by mining companies to level en-tire mountains of rock containing only small concentrations of gold. To extract the gold, miners spray a solution of highly toxic cyanide salts (which react with gold) onto huge open-air piles of crushed rock.

Water use and energy consumption in mining have been identified as two key business risks by the mining industry. Further, it is identified that future availability of water supply is a significant risk for the hard rock mining sector and a range of treatment methods for mitigating the impending risk are essential as competition for access to water increases with increased demand [].

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).
