Jan 20, 2021· The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (waterrepel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents Frothers (MIBC) is what allows the formation of air bubbles.

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.

Jun 15, 2018· The total copper recovered from its ore through flotation process is about 56% 6,18, which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.20.4%) than that of lowgrade ores (0.20.3%).
