Mineral Processing Wastes

About 450 million metric tons (500 million tons) per year (1) of mill tailings are generated from copper, iron, taconite, lead, and zinc ore concentration processes and uranium refining, as well as other ores, such as barite, feldspar, gold, molybdenum, nickel, and silver. Mill tailings are typically slurried into large impoundments, where they gradually become partially dewatered.
