Froth flotation
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

At Blagodatnoye, the gold content in the flotation tails in g/t stood at 0.19 before flash flotation was introduced and 0.17 after, a fall of 11%. One SkimAir flash flotation unit has been installed in Blagodatnoye Mill 4, with an additional unit being installed in 20182019; and another four ordered as part of the Mills 1, 2 and 3 expansion
The role of a flash flotation circuit in an industrial
The distribution of valuable material in the cyclone overflow stream (conventional flotation feed) undergoes a step change when the flash circuit is taken offline with an increase in the amount of valuable fines being generated, which is further reflected in the flotation tails with a higher proportion of both pyrite and gold being present in

Gold Flash Flotation and Gravity Recovery Gold Ore Crusher
In the first section, the use of gravity to recover coarse gold and flash flotation to recover fine gold and sulphides is discussed. The most frequent joint application of the two recovery methods is the use of gravity recovery to recover GRG from the flash flotation concentrate.
Flash flotation an introduction AusIMM Bulletin
Typical applications of flash flotation can be found in gold, silver, platinum and other PGMs, lead, copper, nickel, and combinations thereof. It is worth noting that typically flash flotation is not extensively evaluated during a feasibility study and hence it is unknown if it would be suitable for the project ore and mineralogy.
Productive froth flotation technology FL
Results show that our flotation machines operate on exceptional grade recovery curves, with respect to coarse and fine particle recovery. The remarkable performance of our machines is related to flotationfavourable hydrodynamics, which produce higher active cell volumes, provide longer residence times, and complement froth removal.
