Environmental Impacts Of Gold Mining Brilliant Earth

Toxic Waste. Modern industrial gold mining destroys landscapes and creates huge amounts of toxic waste. Due to the use of dirty practices such as open pit mining and cyanide heap leaching mining companies generate about 20 tons of toxic waste for every 0.333-ounce gold ring. The waste usually a gray liquid sludge is laden with deadly cyanide .
