flotation cell rotor. Traditionally flotation plant design blower selection and control has been based on using an oversized positive displacement blower, or an industrial fan, with any excess air discharged to atmosphere. While easy to select and design, this type of circuit contains inefficiencies especially when it comes to energy consumption.

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 ...
