Flotation Method Minerals

flotation process | Infoplease

flotation process, in mineral treatment and mining, process for concentrating the metalbearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.
