Froth flotation  3

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.

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.

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.
