China’s non-ferrous metals, rare metal ore beneficiation production, the use of electric election was started in 1964. Currently used for the selection of crude tungsten and tin concentrate, replacing the particle float; selection of rare metals are also gradually promote the use of, and achieved some success. In recent ten years, there has been a great development in the selection of incoming calls in foreign countries. Not only the selection of non-ferrous and rare-metal ores but also the selection of black and non-metallic ores has also been applied.
