Each cell of the flotation machine contains an impeller, which is a rotating device responsible for stirring the slurry. The impeller creates a turbulent environment in the cell, ensuring thorough mixing of the reagents and ore particles. Air Supply. Air is introduced into the flotation cell through various mechanisms, such as blowers or spargers.

After the pulp and flotation reagent are fully mixed, they are sent to the flotation column through the central feeding device. The pulp is slowly descended under the action of gravity, and the compressed air is dispersed into a large number of tiny bubbles through the inflator, which are evenly distributed on the entire section of the column and rise slowly.

Dual-chamber flotation machines are not new. Early forms of the modern dual-chamber pneumatic cells can be traced back to the early 1960s [].Their primary characteristic is that—unlike mechanical flotation cells where the gas-particle adhesion occurs in an agitated, aerated tank—most of the gas-particle adhesion takes place in a separate, high-intensity …
