Toxic WasteAcid Mine DrainageMercury PollutionDestroying The Modern industrial g 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 0.333ounce g ring. The waste, usually a gray liquid sludge, is laden with deadly cyanide and toxic heavy metals. Many g mines dump their toxic waste directly into natural water bodieSee more on brilliantearth Chat
