How To Use Sodium Cyanide For Gold Tailings

  • how to used sodium cynide for gold tailings

    Cyanide is also incredibly helpful for processing gold. At the Stibnite Gold Project, we will use a weak sodium cyanide solution to extract gold from the ore we mine. Cyanide has a natural tendency to bond with metals, even when they occur in microscopic amounts, such as gold and silver in ore.
