stage specialization for design and analysis of flotation,flotation circuits. the size of the entering particles and the types of streams including pulp and froth were considered as the basis for specialization of the flotation processes. in the new approach, the flotation process plays as the two functions of primary and secondary concentrations. the proposed approach was applied to a lead flotation.particle size reduction, screening and size analysis,particle size reduction, screening and size analysis objective particles can interfere with separation processes, such as froth flotation, and might result in loss of valuable components. in other operations, the objective might be to produce very fine particles..
