Regulation of bubble size in flotation: A review
Subsequently, bubbles collide with the mineral particles in the flotation cell, and the hydrophobic particles adhere to the bubbles, rising to form a froth layer, whereas the hydrophilic particles sink to the bottom of the cell to form a tailing [[11], [12], [13]]. The interaction process of bubbles and mineral particles is therefore considered ...
Mixing and gas dispersion in mineral flotation cells
Mineral flotation in mechanically agitated vessels (cells) involves complex interaction between bubbles, particles and the liquid phase.Ideally, just enough power input from the impeller is needed to so that the frequency of particle–bubble collision and attachment is maximised, while at the same time detachment events are minimised. This …

CDF simulation of bubble-particle collisions in mineral flotation cells
Abstract. The efficiency of the flotation process depends highly on the initial contact between the air bubble and the mineral particle. To enhance this contact, flotation cells are designed to achieve good mixing between the suspending solids and the dispersing air. CFD simulation of flotation cells provides an opportunity to analyse the ...
