Flotation cells for profitable minerals concentration
The basic module of the WEMCO 1+1 flotation system is a cell consisting of a single tank and mechanism. Several cells are bolted together to form a flotation machine with feed, connection and discharge boxes as required. Pulp level in the tanks is controlled by automatically operated dart valves in the connection and discharge boxes.

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

A Review of Flotation Physical Froth Flow Modifiers
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the …
