  • How can metal mining impact the environment? American

    As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in areas nearby. Waste piles from processing, such as tailings impoundments, leach piles, and slag piles vary in size, but can be very large.
