Abstract Conditions for increasing flotation process intensity and selectivity are considered. It is proposed to create optimal hydrodynamic conditions separately in flotation cell different spatial zones for different flotation sub-processes. Number of zones depends on type of processed feed material. Extremal relationship between water-cleaning degree and reactor retention time has been determined.
keywords Multi-zone pneumatic flotation machines, reactor-separator, hydrodynamic regimes, retention time.
