15/06/2019· A new approach for flotation machine selection is proposed. VIKOR and TOPSIS methods were used for the evaluation of flotation machines. Criteria for the evaluation were selected and weights were signed by three experts. Based on the performed evaluation, the best solution was selected.
01/10/2010· For coarse particles, a new type of flotation cell based on the principle of fluidization has been developed. Fluidization can provide a gentle fluid mechanical environment that is favourable to the retention of the bonds between bubbles and coarse particles, and particle detachment can be minimised.
Download Citation New directions in flotation machine design The theoretical background for flotation kinetics of ultrafine and coarse particles are explored.
The introduction of fluidised bed design minimises the turbulence within flotation cells, which greatly reduces the detachment of coarse particles from air bubbles . The froth layer occurring in conventional flotation is also minimised in the HydroFloat Separator to further prevent the detachment of particles crossing through the pulp froth

The Wemco unit is a naturally aspirated mechanical flotation machine. Air is induced via a standpipe and an inlet pipe open to the atmosphere. For Wemco flotation machines of constant rotor diameter, hydrodynamic parameters are defined as the relationship between air ingestion and primary liquid circulation as functions of rotor submergence, rotor engagement, and rotor
Turbulence in mechanical flotation cells, achieved via an impeller, plays a key role in keeping particles in suspension, dispersing air bubbles and promoting particle bubble collision. However ...

The objective of the present study was to develop a procedure for flotation circuit design that accounts for uncertainty and water efficiency. The design process considers two stages: 1) optimal process design without considering water consumption and 2) efficient use of water considering property integration.
