Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water). Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold. In gold mining, froth flotation is used ...

After the precious metals have been dissolved into solution, the ore tailings are filtered and discarded. The pregnant leach liquor is pumped to a holding tank where it is subsequently reacted with a solution of sodium hydroxide and sodium borohydride at a pH of 8.2 to 8.6 and the oxidation-reduction parameter held at -550 to -650.

Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold's hydrophobicity. This mixture is placed into a large tank filled with distilled water.

Froth flotation is a process for selectively separating of 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.

In the first stage of filtration-based mining, ore is crushed and ground, after which the fine ore is mixed with water in froth flotation cells, which serve to extract precious metals. The resulting tail froth is thickened in a sedimentation tank, where the overflow is water and the underflow contains concentrated ore paste.
