"The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories of hydrophobicity that are …
The deposit contains copper, iron, lead, zinc sulfides along with gold. Their concentrator has flexibility to produce gold doré (a semi-pure concentrate of gold and silver) and separate copper, lead, and zinc concentrates depending on the stockpile blending. In this study, the chosen processing route was to produce a copper concentrate. 2.1.1.

The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80% of copper from ore is generated using flotation, smelting and refining.
The flotation method is a widely used technique for the recovery of gold from gold-containing copper ores, base metal ores, copper-nickel ores, platinum group ores and many other ores where other processes are not applicable. ...

Flotation kinetic behavior of two deposits including an elevated-pyritic (Cu/S=0.21) complex copper sulfide ore and a high-grade carbonaceous sedimentary apatite (P2O5>25%) ore were investigated.
Copper is most commonly present in the earth's crust as copper-iron-sulphide and copper sulphide minerals, for example, chalcopyrite (CuFeS 2), bornite (Cu 5FeS 4) and chalcocite (Cu 2S). Copper also occurs to a lesser extent in oxidised minerals, for instance, malachite (Cu 2(OH)CO 3), azurite (Cu 3(OH) 2(CO 3) 2) and chrysocolla (CuO.SiO₂).
