    The native copper would tend to float in the scavenger circuit, but would tend to concentrate itself in the regrind circuit, and often fell out in the recleaner circuit (if it made it that far!) They installed a "bleed" line in the regrind circuit, to take a portion and send it to a separate small float circuit, where they attempted to recover as much of the native copper, which was then16/05/2016· The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation The flow sheet depends on the mode of occurrence of the mineralCopper Flotation Mineral Processing & Metallurgy16/05/2016· Instead, leach contact with straight acid for four days now deals with the oxidic copper, leaving clean sulphides to be recovered by flotation Ray (Kennecott) has developed a LPF flowsheet for recovering oxidic copper The values include chrysocolla, cuprite, malachite, tenorite, and native copper The carbonate, silicate, and sulphate are the main objects of attack CopperCopper LPF Leach Precipitation and Flotation Process
