Principal factors affecting hydrodynamics in flotation. Unlike single-phase liquid, flotation pulp is a complex three-phase system of water, solid, and gas. The presence of dispersed gas and solid phases makes the fluid flow patterns in flotation cells non-uniform and complex (Koh and Schwarz, 2007, Schwarz et al., 2016).
