Basic Flotation Circuit Design
The slurry flow then enters the feed end of the flotation cells. The slurry at this point is called the HEADS of the circuit. The mineral is then separated and flows over the overflow into a trough called a flotation cell LAUNDERER. The OVERFLOW is now called the flotation CONCENTRATE of the circuit.

In some cases it could be useful to employ two different kinds of anemometers depending on the flotation cell. For instance, a vane anemometer can be considered to determine the air velocity for induced-air cells. A hot wire anemometer is an interesting option to evaluate the air inlet in forced-air flotation cells.

Improving flotation energy efficiency by optimizing cell hydrodynamics
3.4. Effect of cell hydrodynamics on flotation performance. Overall recovery (R O) in a flotation cell is a function of recovery in the collection (R C) and froth (R f) phase, Eq. (4), ( Dobby, 1984 ): (4) R o = R f R c R f R c + 1 - R C. The drivers of recovery are very different in these two phases.

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.

Flotation is also the best method for recovery of gold from base metal ores and gold-containing PGM ores. Excluding gravity preconcentration, flotation remains the most cost-effective bene ficiation method. Gold itself is a rare metal and the average grades for low-grade deposits vary between 3 and 6 ppm.
