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.

The process design of gold leaching and carbon-in-pulp circuits contaminants. These are removed by thermal regeneration of the eluted carbon, typically in a rotary kiln at temperatures of 650750°C. Regeneration is carried out in a steam atmosphere to minimize carbon degradation due to oxidation.
Combining higher concentrations of gold or silver with high cyanide and high oxygen amounts intensifies the chemical leaching reaction to maximise mineral recoveries. This type of leaching is best used for gravity concentrates, such as from the IPJ, or the Python plant, or flotation concentrates. How It Works
