貴金屬礦物泡沫泵浮選時常用的浮選機有以下幾種。

葉輪揣挫式浮選機

這是一種用輻射式葉片的葉輪進行攪拌充氣的浮選機。我國廣泛應用的是國產(chǎn)XJK型浮選機，其充氣量大，生產(chǎn)能力大，檢修方便。葉輪攪拌式浮選機與浮選柱比較，具有攪拌力強、藥劑消耗少、可以處理粗顆粒密度大的礦粒、能適應復雜流程、應用范圍廣、指標較穩(wěn)定等優(yōu)點。缺點是AF泡沫泵構造復雜、功率消耗大、液面不穩(wěn)定、充氣量小等。

There are several kinds of flotation machines commonly used for flotation of precious metal mineral foam pumps.

Impeller scuttle flotation machine

This is a kind of flotation machine which uses the impeller of radial vane to stir and inflate. XJK flotation machine is widely used in China, which has large gas filling capacity, large production capacity and convenient maintenance. Compared with the flotation column, the impeller agitated flotation machine has the advantages of strong agitating force, less reagent consumption, large density of coarse particles, adaptability to complex process, wide application range and stable index. The drawback is that the AF foam pump has complex structure, high power consumption, unstable liquid level and low aeration volume.
