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 ...
