Abstract: In a deinking process for a fibre stock or slurry air is introduced into the slurry so that air bubbles and ink come into contact, and the ink-laden bubbles are then separated from the slurry. 
<??>In order to provide an improved separation process the invention proposes to independently control the air injection, the mixing of the air and slurry, and the separation process by splitting them into separate steps so as to optimise the separation process. 
<??>Thus, there is provided a separation cell (31) which is fed with slurry from an inlet, an air inlet device, which in one embodiment comprises a porous sintered sleeve (7) to which air pressure is applied, and a mixing section which imposes turbulent flow on the air bubbles and slurry by passing the constituents through a series of turbulence discs (39). The resulting mixture enters the separation cell where the ink-laden bubbles rise to the surface as a foam which is conveniently removed by suction. The reinked slurry being drawn off from the separation cell.
