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 ....
Sep 23, 2018· We have some copper tailings in large quantity and as per the analysis there is roughly 29 grams per ton of Gold and some other metals such as Iridium, Platinum and Palladium Can anyone suggest what would be the best method of extracting the gold, iridium, platinum and palladium separately from the entire lot?...
Additionally, Molycorp stores their radioactive waste in contained paste tailings facilities in a solid state as opposed to allowing it to seep into the surrounding ecosystem as radioactive sludge (Davis 2012) These developments have decreased the cost of the refinement process as well as the negative environmental impact...
copper SX-EW in order to make LME Grade ‘A’ specification The copper flotation step is inherently inefficient for cobalt, with recoveries typically from 40% for oxides up to 80% for sulphides, so there is a substantial amount of cobalt contained in tailings dams that could be recovered – eg the Kolwezi Tailings Project...
