  • Copper Flotation Mineral Processing Amp Metallurgy

    may 16, 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.sep 20, 2019 thus it can be seen that the complexity of the froth flotation process is highly, and both of preliminary ore grinding operation and froth flotation separation process are very important. So it is recommended to do a professional flotation process design before putting it into production. only in this way can a good flotation index be guaranteed.
