Tailings - Wikipedia
Terminology. Tailings are also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra-cone (terrikon).. Examples Sulfide minerals. The effluent from the tailings from the mining of sulfidic minerals has been described as "the largest environmental liability of the mining industry". These tailings contain large amounts of pyrite (FeS 2) andChilean researchers want to turn copper tailings into,,Dec 28, 2021· The new technique involves transporting fresh tailings to a near or on-site treatment facility, fine grinding and particle size classification of the tailings for surface activation and early sand,Uranium mining - Wikipedia,Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tonnes per year included Namibia,Operations Overview | New Century Resources,Following the depletion of the original ore reserve, the mine was put on care and maintenance in 2016.
