Investigation of bubble-particle attachment,

This means that any effect of superficial gas velocity on flotation rate constant was due to changes in the number of bubbles and collision frequency. The flotation rate constant, collision frequency, and the number of bubbles increased with increasing impeller speed. However, collection efficiency decreased with increasing impeller speed.

Investigation of bubble-particle attachment,

2020-9-20  It is well known that TKEDR is one of the most important parameters determining the bubble-particle interactions in a mechanical flotation cell [12,30,31,40,41]. Deglon et al. measured TKEDR in a cylindrical tank of standard geometry, agitated by a Rushton turbine and a novel high-speed spinning disc. The results indicate that TKEDR for the Rushton turbine is approximately 30 times higher than
