Minerals | Special Issue : Flotation in Mineral Processing

31.10.2016· Thus, flotation initially originated from the field of mineral processing, usually termed “froth flotation”; a typical application is certainly with sulphide minerals. For many years, various particulate solids, in addition to minerals, have been extracted from water by using this effective process. These flotation applications mainly include the treatment of water and wastewater, as well,Volcanogenic massive sulfide ore deposit - Wikipedia,Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and created by volcanic-associated hydrothermal events in submarine environments.. These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits.
