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.
  Flotation is non-metallic minerals such as graphite, sulfur, diamond, quartz, mica, feldspar, silicate minerals, non-metallic salts such as fluorite, apatite, barite, and soluble salts such as potassium salts and rock salts. The selection of minerals. Another important use of flotation is to reduce ash in fine coal and to remove fine pyrite from coal. There are billions of tons of ore and materials that are processed by flotation every year in the world. The large ore processing plant processes 100,000 tons of ore per day. The production index and equipment efficiency of flotation are high. The recovery rate of selected sulfide ore is above 90%, and the concentrate grade can be close to the theoretical grade of pure mineral. The use of flotation to treat polymetallic symbiotic minerals, such as copper, lead, zinc and other polymetallic ores can be separated from copper, lead, zinc and pyrite, and can obtain high selection indicators.
Flotation is suitable for the treatment of fine-grained and fine-grained materials. It is difficult to recover fine ore particles of less than 10 μm by other beneficiation methods, and it can also be treated by flotation. Some flotation technologies that specialize in the treatment of very fine particles have a lower particle size lower limit. Ultra-fine flotation and ion flotation technology can recover various substances from colloidal particles to molecular and ionic states. Flotation also selects intermediate products of pyrometallurgy, useful components in volatiles and slag, processes hydrometallurgical leaching slag and displaced precipitated products, and recovers chemical products (such as pulp, surface active substances, etc.) and wastewater. Inorganic and organic matter.
