Jul 23, 2014· July 23, 2014. Most methods of water-based gold extraction are dependent on gold's lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with …

The basis of froth flotation is the difference in wettabilities of different minerals. Particles range from those that are easily wettable by water (hydrophilic) to those that are water-repellent (hydrophobic). If a mixture of hydrophobic and hydrophilic particles are suspended in water, ... oxide minerals. + + + + + - - - - - -- +-+ + +--(A ...

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. It has been described as "the single most important …

Jan 01, 2016· Pyrrhotite floats best in acid circuits. The pH range for flotation for gold sulfide ores containing pyrite and arsenopyrite is generally between 7 and 9. Flotation may be carried out at higher pH values of 9–10, since this favors the depression of talc minerals and avoids the use of expensive gangue depressants.

Froth Flotation. Literature: Flotation is the most versatile mineral processing technique that has made it possible to mine most low grade & complex ore bodies that would have been regarded as uneconomic. Though complex and not completely understood, flotation has been used to achieve specific separations from complex ores like Pb-Zn-Cu, Pb-Zn ...

Feb 06, 2018· Aided by the surfactant, the water repels the gold into the air bubbles, which rise to the top – creating a bubbly golden froth. The froth is skimmed from the surface and collected and later condensed into metallic gold. Meanwhile, the tailings and waste material sink to the bottom of the tank. Along with mechanized mining equipment, froth flotation …
