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.

Gold-Pyrite ores - Danafloat

Free gold flotation fundamentally is not possible because gold is a noble element which means it is a chemically nonreactive metallic. Since sulphide flotation collectors chemisorb to the target mineral surfaces, because noble metals do not react, collector adsorption on a pure gold surface is not possible.
