Copper Flotation
2016 5 16 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.
