  • Introduction to flotation machine for gold, copper, zinc

    Flotation machine is applicable for the separation of nonferrous metal and ferrous metal. It is also used for separating nonmetal, such as fluorite and talcum.
    The impellers are driven through V- belt transmission, which brings centrifugal effect to form the negative pressure. On the one hand, the flotation machine inhales sufficient air to mix with ore slurry; on the other hand it stirs ore slurry and mix with medication to form the mineralized froth. By adjusting the height of flashboard to control the liquid level and make the useful froth scraped by loam board.

     

    Features of flotation machine for gold, copper, zinc
    1)The floatation machine has the advantages of large air-absorption capacity and low energy consumption.

    2)Every cell owns three functions: air absorption, slurry absorption, and floatation separation, and the cells form a floatation separation loop by itself without any auxiliary equipment, and is allocated horizontally, which favors the change of flow.

    3)The circulation of mineral slurry is reasonable, and can avoid the disposition of coarse sand to the largest extent. There is self-control device on the surface of mineral slurry, so it is easy to adjust it.

    4)The impeller has backward-inclined upper and lower vanes, which produce upper and lower circulation of mineral slurrry respectively.

     

    Working principle of flotation machine for gold, copper, zinc

    When flotation machine works, slurry is inhaled from the bottom of the trough to the space between impellers. Meanwhile, the low_pressure air send by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole trough. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the re-mis with air. The remained slurry flows to the next trough until becomes residue.

     

    Operation Instruction of flotation machine for gold, copper, zinc

    To check the bolts before starting the machine and to use hand instead of impellers to prevent the sediment from adding the burden of electromotor. To adjust the height of strobe carefully to keep the stabilization of liquid level and scrape the mineralized froth to the launder. The impellers and stators should have a distance and should be changed when they are worn. The bearing in the pump should be maintained every three months.
