flotation cells are listed in able 1.t the rougher/scavenger flotation circuit consistently recovers 91% of the total copper sulphide minerals, with the greatest loss typically being from the >75µm and <7µm size fraction. the enrichment ratio on the rougher/scavenger flotation stage is around 4.5 to 5.0. the

Froth flotation : definition of Froth flotation and ...

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.
