Flotation - an overview | ScienceDirect Topics

1.12.5 Flotation. Flotation is a separation process in which air or gas bubbles are directed at the solid particles and then drive these particles to the liquid surface. Flotation is more beneficial and efficient for removing cells than sedimentation. Flotation can capture particles smaller than 500 μm in diameter (Chen et al., 2011).

on the top of the flotation cell rather than mixed with the pulp prior to flotation (DeLozier et al, 2005). Laboratory and pilot plant experiments have demonstrated improvements in the flotation process. It is suggested that mixing the surfactant into the pulp before flotation may cause surfactant to adsorb to the pulp fibers making them more
