·In this study the effect of mixtures of copper slag and flotation tailings from copper mine Bor Serbia on the flotation results of copper recovery and flotation kinetics parameters in a batch flotation cell has been investigated By simultaneous adding old flotation tailings in the ball mill at the rate of 9% it is possible to increase copper recovery for about 20%
·Legacy base metal mines host a complex variety of waste materials which can severely degrade the environment Lottermoser et al 1999 Gore et al 2007 Venkateswarlu et al 2016 Non ferrous slag is a waste material produced during the smelting of base metals nickel copper zinc lead and some precious metals such as silver often with large
·Currently CMP operates two underground copper mines that are located on the same tenement Chibuluma South Mine which was commissioned in 2005 and the Chifupu mine whose development started in 2012 with ore production starting in 2016 Recovery of copper from slag by froth flotation is easy to implement but yields a lower recovery due
Piece of black slag from the Douglas Arizona Smelter where the copper ore from the Bisbee mines was processed from 1902 until it closed in 1987
·Copper plays a vital role in modern life which is irreplaceable for daily infrastructure and technologies [1] [2] However despite the finite copper resources on the Earth global copper production continued increasing over the past century [3] [4] Although we are far from approaching geological stocks for potentially mineable Cu resources the economic
·The slag pile in Anaconda is a byproduct from the town s copper smelting history and is part of the town s Superfund site For over a half century companies have tried but often failed to
·mining sectors involving copper slag from as far as Chile and T urkey still investigating the reclamation of valuables from copper slag [8 20] Botswana faces similar problems with
·One of the greatest environmental challenges in metal extraction is the generation of a large amount of slag Most of these slags contain insufficient amounts of valuable metals for economical revalorization but these concentrations may be harmful for the environment At present more than 80% of the global copper products are obtained by the
·Copper occurs in nature in the form of sulphide and oxide ores salt minerals and as native copper It is the second most used non ferrous metal in industry Boulamanti and Moya 2016 According to the United States Geological Survey USGS the 2019 global annual copper extraction was about 20 million tons Fig 1 The highest annual mining capacity was recorded
