The froth collected from a series of rougher cells is then passed to a set of cleaner cells to further raise the copper sulfide concentrations (Fig. 13.5). The gangue-rich underflow from the rougher cells is passed through a series of scavenger cells to collect any residual copper sulfide values not picked up by the rougher cells.

Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings.

Froth flotation - The Full Wiki

Froth flotation is one of the processes used to recover recycled paper.In the paper industry this step is called deinking or just flotation. The target is to release and remove the hydrophobic contaminants from the recycled paper. The contaminants are mostly printing ink and stickies. Normally the setup is a two stage system with 3,4 or 5 flotation cells in series [4].
