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 ...

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.

for most feldspar ore beneficiation. Figure 11.27-1 shows a process flow diagram of the flotation process. The ore is crushed by primary and secondary crushers and ground by jaw crushers, cone crushers, and rod mills until it is reduced to less than 841 µm (20 mesh). Then the ore passes to a three-stage, acid-circuit flotation process.

FLOTATION PROCESS Flotation is a method of separating an ore species froth another, based on its hydrophobic surface characteristics either natural or induced when present as a suspension in water with air bubble. Due to the affinity of the desired mineral to adhere to air bubbles it is floated out of the ore slurry.
