Flotation concentrator

Widely applied flotation separation process
Flotation separation process is used for separating ferrous and non-ferrous metals. It can be also used for separation of non-metal materials such as coal fluorite and steatite. The impeller rotates by triangle belt of the motor, with produces centrifugal function and causes negative pressure.0n one hand it draws in enough air mixed with ore magma; on the other hand it agitates to mix ore magma with chemical medicines. At the same time, it minifies bubbles so that minerals can stick above them .float on the surface of magma, and form mineralized bubbles. The height of plate can be adjusted to control fluid level so that the available bubbles can be scrapped out by scrapers.
Structure and Application of Flotation Concentrator
This type of flotation concentrator is formed by U through solid, hollow shaft inflation, suspension rotor and new type impeller. The cone impeller lean backwards, the blending quantity is big and the pressure head is small. The advantages are simple structure and low energy consumption. Inside the impeller, there is air distributor, which distributes air into most parts of impeller evenly.

When flotation plant 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-mix with air. The remained slurry flows to the next flotation-cell until becomes residue.
