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.

Platinum group metals contained in copper-nickel and nickel ores are extracted using flotation. Solvay's research has established that the highest recoveries of these metals are achieved with a combination of our brand chemistries, AERO®, AEROFLOAT®, AEROPHINE® and OREPREP® including our new AEROFLOAT MX 500 collector.
