Toxic chemicals used to extract the valuable materials from the ore such as the cyanide used in gold mining remain in the tailings at the end of the process and may leach out into ground water. Rock may naturally contain dangerous chemicals such as arsenic and mercury which leach into water much more readily after rock has been ground up and exposed to the wind and
