C. Jiang J. Ma in Encyclopedia of Separation Science 2000 Evolution of Flotation Cells. Froth flotation is the most widely used separation process in modern paper mills. During the last 10 years the development of flotation de-inking cells has been pursued more aggressively than the technologies of any other segment of the pulp and paper industry.

Nov 04 2013 Froth crowders for both the Wemco and Xcell flotation cells direct the slurry flow from the centre of the flotation cell to the periphery launder which decreases froth residence time. All three design modifications increase the probability of bubbleparticle aggregates surviving the froth phase.

Particles enter the froth phase when a bubble carrying the particles crosses the pulp-froth interface. The froth phase floats on top of the pulp phase and is formed by the bubbles that break through the surface of the pulp phase. The water in the flotation cell is conditioned to promote the formation of a more or less stable froth.
