Froth Flotation

Froth flotation is a process used in mining to separate valuable minerals from ore. It works by adding chemicals to a slurry of crushed rock that create bubbles. The target minerals attach to these bubbles and rise to the surface, forming a frothy layer. This froth is then skimmed off, while the waste material, or tailings, sinks to the bottom. This method efficiently concentrates valuable metals, like copper or gold, making it an essential technique in mineral processing and recycling.
