Levels in flotation cells are conventionally controlled by PI (proportional and integral) control loops. PI control will 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.

Flotation machines constitute the basic equipment for useful minerals recovery from non-ferrous ores and other raw materials by flotation. They can operate also as individual flotation cells. Flotation Cells (Froth Flotation) were developed to separate and recover high-value Sulphide ores from low-grade ore bodies. The Flotation Cell is aerated to produce bubbles and agitated to …
