Valuable minerals in ore can be separated from each other and from worthless components by the froth flotation process. Flotation is a key process in the recovery of most of the world's copper, lead, molybdenum, nickel, platinum group elements, silver and zinc, and in the treatment of certain gold and tin ores. EURUS multistage centrifugal blowers ( turbo blowers ) are used to supply forced air creating small air bubbles which attach to the conditioned ore particles. The bubbles float to the surface and form a valuable froth layer. EURUS multistage centrifugal blowers are the most well known brand names in the flotation cell industry and have the best reputation for longevity and service. Multistage centrifugal blowers ( turbo blowers ) typically operate at higher elevations and range from 3,000 to 20,000 cfm and generally in the 4-7 psi range.
