Froth flotation is a process of using bubbles to separate minerals based on their relative affinity for water. Bubbles are induced in the slurry through aeration.
Ultrafine coal is normally treated by means of froth flotation, but this is practised to a very limited extent in South Africa. The distribution of mineral matter in coal determines the efficiency of its washing.

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 froth must travel …
Froth flotation has been used extensively in the past to beneficiate fine coal (nominal minus 0,5 mm) in Natal, as well as at Grootegeluk in the Waterberg coalfield. In most of these cases, the …

Froth flotation has demonstrated significant potential for concentrating base metals from oxidised ores. The most common method used for flotation in such cases is sulphidisation. However, this approach comes with drawbacks, notably environmental pollution, and a lack of comprehensive understanding of its underlying chemistry.
Froth flotation method has been an important part of the concentration process since the 1920s and today, more than half of the world's marketable phosphate is produced by froth flotation. ... applied in the industry have certain limitations and disadvantages when compared to flotation. Some carbonate rich phosphate deposits are processed by ...
Froth flotation is a physicochemical separation technique that exploits the difference in the surface wettability of mineral particles (Wills and Finch, 2016).From a heterogeneous mixture of solids, hydrophobic particles are made to attach to gas bubbles and subsequently carried to the froth phase and recovered as a froth product (typically the value mineral …

South Africa is the largest supplier of platinum group metals (PGMs), which are mined from three reefs in the Bushveld Igneous Complex. About 60% of the world's mined PGMs come from a single reef, the UG-2 reef (Mudd, 2010). Flotation is the primary method used to concentrate the PGMs. There are
Other beneficiation methods such as calcinations, acid leaching, and magnetic separation are also being practiced in the industry; however, they have certain limitations and disadvantages when compared with flotation. Froth flotation for the separation of phosphate min- erals from other gangue minerals has been practiced by fatty acid flotation ...

Being a South African metallurgical laboratory, we also offer flotation tests for sulphides. Zinnwaldite and lepidolite are becoming increasingly popular as alternative lithium sources. Lithium demand is expected to increase substantially over the next decade.
Froth flotation is used widely for upgrading raw phosphate. The flotation recovery of coarse phosphate (−1.18+0.425 mm) is much lower than that achieved on the −0.425+0.15 mm size fraction.
The performance of the froth phase, usually evaluated as froth recovery determines overall flotation performance. In most flotation operations, recovery across the froth is rate controlling; …
