Froth flotation - Wikipedia

2019-10-15  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.

1. Introduction. Since early 20th century, froth flotation has been frequently used for the separation of solids encountered particularly in the primary mineral and chemical industries [1,2].In the flotation process, the addition of flotation agents could significantly enhance the differences in the surface properties of mineral particles to improve the separation efficiency [3,4].
