Copper Flotation - Mineral Processing & Metallurgy
In one or two plants employing two-stage grinding, improved results have been obtained by separating the slime from the primary ball mill circuit and sending it direct to a special flotation section. This method is useful when the feed to the flotation plant contains an appreciable quantity of fines, which, due generally to oxidation through exposure, require different treatment from the unweathered part of the ore.

Deinking - Wikipedia
Normally the setup is a two-stage system with 3, 4 or 5 flotation cells in series. Flotation deinking is very effective in removing ink particles larger than about 10 µm. Wash deinking. Wash deinking consists of a washing stage where dispersants are added to wash out the printing inks.

Copper Ore Crushing, Grinding & Flotation
Flotation consists of one stage of rougher flotation of three cells, three stages of rougher scavenger flotation and one stage each of cleaner (3 cells), recleaner (2 cells) and cleaner scavenger flotation (3 cells). Retention times in the individual flotation stages are as shown in Figure 5, Flotation Stage Retention Times.
