Tailings dam Wikipedia

A tailings dam is typically an earthfill embankment dam used to store byproducts of mining operations after separating the ore from the gangue. Tailings can be liquid, solid, or a slurry of fine particles, and are usually highly toxic and potentially radioactive.Solid tailings are often used as part of the structure itself. Tailings dams rank among the largest engineered structures on earth
