    To overcome this constraint, a new stirrerless cone-shaped flotation cell was developed in Germany (Bahr, 1982), now called the Pneuflot. This cell uses a novel aeration technique in which minute bubbles are introduced into the slurry before it reaches the cell. The upper particle size is restricted to 300 μm.
