Many modern mines now use a de toxification process that converts cyanide into the less toxic cyanatebining it with the mine tailings waste. In addition, the majority of cyanide gold mines use impermeable liners in their tailings ponds and underneath their heap leaching operations. However, leaks and tears in these liners have been a continual problem at many mines. Mining
