Froth flotation is an important concentration process that can be used to selectively separate hydrophobic materials from hydrophilic waste gangue. In a more simple context, froth flotation is one of the most popular operational processes for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which commercially ...

In circuits that utilize flotation plus gravity, the economics of the gravity portion of the circuit are generally very strong. According to Dr. André Laplante (Laplante, 2005) the benefit for every 10% of recovery by gravity usually falls in the range of +0.5-5% of additional overall gold recovery.

Flotation Circuits for Air-Lift and Pneumatic Cells An air-lift machine can often be run as a rougher-cleaner cell, as in circuit No. 5 (Fig. 52), by taking a finished concentrate off the first few feet and returning the froth from the rest of the machine to the feed end. This method is also applicable to pneumatic cells, but its use is not common.

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.

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. The mineral has been separated from the ore, there for it is in a concentrated form from the original.
