Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.
Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide , which can then be activated by the froth flotation plant.

Froth flotation to separate plastics, Argonne National Laboratory. Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.
After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: Ratio of concentration % Metal Recovery % Metal Loss % Weight Recovery, or % Yield Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation
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.
