Deinking flotation cell

flotation deinking has been considered. Experimental methodology Old uncoated magazine (OMG) maplitho paper is used for this study. The paper is slushed in a hydropulper and subsequently flotation is carried out in a flotation cell, to remove the separated ink in the form of foam. The principle and equipments have been discussed in our earlier
