  • Tailings dam Wikipedia

    A tailings dam is typically an earth-fill 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.New global tailings standard guidelines aim for zero harm,Aug 06, 2020· The guidelines, organized around six topic areas, 15 principles and 77 auditable requirements, add new requirements for independent oversight of tailings facilities design
