Flotation equipment is a kind of beneficiation equipment which takes bubbles as the carrier and uses the difference in mineral surface wettability to separate minerals. In the late nineteenth century, flotation as a beneficiation method was explicitly proposed, and various types of flotation equipment were developed, including flotation …

work well when the cell being controlled is isolated. However, flotation cells are connected in a network and the tailings stream from one cell is likely to be fed to another cell. Similarly, the concentrate flows will generally be fed into banks higher up in the circuit. This results in strong interactions between levels in a flotation circuit ...
