The Advantages Of Cyanide Process For Gold

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 0333ounce gold ring the waste usually a gray liquid sludge is laden with deadly cyanide and toxic heavy metals many gold mines dump their toxic waste directly into natural water bodies.
