    Aug 14, 2017· Grinding is done in closed circuit with classifier.In many instances, superior flotation is results are obtained by conditioning the ore with the reagents before the flotation step. Oily type collectors are sometimes added to the grinding circuit to ensure dispersion.Flotation machines are built in multiple units.

    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.
