Even after having been used for several years in mineral processing plants, the full potential
of the column flotation process is still not fully exploited. There is obviously more than one …

Gas dispersion characteristics are very important to design and selection of flotation process
for the fine particle separation. Although the separation of flotation process heavily depends …

Bubble size distribution, bubble rise velocity, gas and solids hold-up are the extensively
used hydrodynamic parameters apart from floatability data for column flotation design and …

Extractive metallurgy has recently turned its attention to waste treatment for the recovery of
precious metals through innovative metallurgical processes, such as ion flotation. This work …

The recovery of copper in aqueous media by ion flotation in a laboratory flotation cell was
carried out. Hydrodynamics and gas dispersion parameters were obtained. The results show …

Gas holdup has been widely considered as potential parameter for the performance
prediction of flotation column. However, knowledge about gas holdup in presence of solids …

A non-invasive and non-intrusive monitoring techniques are developed based on the signal
capacitance method to observe column flotation performance. In general, gas holdup and …

This work mainly aims on the investigation of phase hold-up characteristics in a column
flotation at different feed solid concentrations performing for an extensive range of working …

The aim of this work is the control of hydrodynamic variables of a pilot flotation column
working with a three-phase system (air-water-ore) in an industrial environment. Since …

The large delay characteristic in the flotation process brings difficulties to the optimal
operation of the flotation process. It is of great significance to estimate the lag time of the …
