Tailings dam Wikipedia
2020-06-01· 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. Tailings dams rank among the largest engineered structures on earth
What are tailings dams? IndustriALL
In 2015, the Samarco dam collapse in Brazil released 33 million cubic metres of iron ore tailings slurry into the environment, killing 19 people, displacing 600 families and contaminating waterways for 620km downriver until it reached the ocean.
