Froth flotation - Wikipedia

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

To Float or Sink: A Brief History of Flotation Milling

Mullen, Idaho used the process on lead-zinc ores in its mill. Because the process was extremely fragile, its use was short-lived. The Idaho mill closed by 1920.14 Froth Flotation The first successful commercial mill using froth flotation was built in 1905 at Broken Hill, Australia, today recognized as the "home of flotation

Froth flotation is a physico-chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite, coal is naturally hydrophobic.

Flotation kinetics of a pyritic gold ore - ScienceDirect

Jan 17, 2011  Research Highlights Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semi-batch flotation. The first order flotation rate constant is independent of particle size in this range. The second order flotation rate constant ...
