What are tailings dams?

Tailings dams are used to store water and waste that come as by products from the mining process It is estimated there are at least 3 500 tailings dams around the world But as there are around 30 000 industrial mines the number of tailings dams is likely to be much higher Tailings dams can be

How can metal mining impact the environment?

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
