Cyanide Use in Gold Mining Earthworks

How is cyanide used in mining? A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold

“In gold mining, a diluted cyanide solution is sprayed on crushed ore that is placed in piles or mixed with ore in enclosed vats,” reports the State Environmental Resource Center (SERC), a project of the non-profit Defenders of Wildlife. “The cyanide attaches to minute particles of gold to form a water-soluble, gold-cyanide

Dirty Gold's Impacts Earthworks

Gold mining is one of the most destructive industries in the world. It can displace communities, contaminate drinking water, hurt workers, and destroy pristine environments. It pollutes water and land with mercury and cyanide, endangering the health of people and ecosystems. Producing gold for one wedding ring alone generates 20 tons of waste.
