An industrial flotation circuit consisting of five parallel rougher flotation banks, each bank provided with 9 cells of 42.5 m 3, was characterized. The air flow rate delivered over the cross-sectional area was directly measured using a simple device that provides a continuous measurement of local gas flow rate. The range of superficial gas ...

The flotation process characterization is typically based on the mineral properties and related to the feed particle size. Laboratory testing allows for the evaluation of the batch flotation kinetics, while plant surveys are carried out for the plant evaluation, and sometimes the rougher flotation stage is also characterized by kinetics, …
