Flotation is application for the separation of nonferrous metal and ferrous metals, such as fluorite and talc.

By adjusting the height of the flash board to control the liquid level, the useful froth can be scraped from the loam board. The height of the strobe must be adjusted carefully to keep the stabilization of the liquid level and the scrape the mineralized froth to the lauder. The impeller and stators should be kept at a distance and should be changed when worn. The bearing in the pump should be maintained every three months. 

When the flotation machine works, the motor drives the impeller to revolve, so the centrifugal effect and negative pressure are produced. On one hand, ample air is absorbed and mixed with mineral slurry, on the other hand, the mixed mineral slurry is mingled with additive, meanwhile, the foams are thinning, the mineral is bounded with foams, and floats up to the surface of mineral slurry and the mineralized foam is formed. The liquid surface can be adjusted with the height of adjustment flashboard, so that the useful foams are scraped with squeegee.
