The next stage after froth flotation is the thickening stage. The froth is poured into large tanks called thickeners. The bubbles break and solids from the froth solution settle at the bottom of the tank. The solids are then filtered to remove excess water, which can be reused in processing additional batches of sulfide ore.
Froth flotation - Wikipedia
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, stone 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 operation used for the recovery and upgrading of sulfide ores". The development of froth flotation …

Gold extraction - Wikipedia
Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values.
