Tailings
Rock and other waste materials removed as impurities when minerals are mined and mineral deposits are processed. These materials are usually dumped on the ground or into ponds. (source: EPA) Background from Wikipedia Tailings (also known as tailings pile, slickens[1] or gangue) are the waste materials left over[2] after removing the minerals from ore. Tailings and gangue represent external costs of mining. As mining techniques and the price of minerals improve, it is not unusual for tailings to be reprocessed using new methods, or more thoroughly with old methods, to recover additional minerals. In coal and oil sands mining, the word 'tailings' refers specifically to fine waste suspended in water and the word 'gangue' is not used.
