Cell Flotation

General Understanding of Cell Flotation

Cell flotation made in our factory can achieve specific separations from complex ores, so it is applied to rough processing and concentration. It is widely used in reverse flotation of non-ferrous metal such as copper, lead, zinc, nickel, molybdenum, ferrous metal and nonmetallic materials.  This flotation separation process includes coarse separation, swept separation, fine separation and flotation, finally the useful ore are reclaimed.

 Cell Flotation

Working Principle of Our Flotation Concentrator

1. After intensively mixed, the pulp and medicaments are fed to the groove bottom of the first tank.
2. When the impeller of the flotation machine begins to rotate, negative pressure is formed, making the air and pulps at the bottom and middle part of the tank enter the mixing zone. The pulp, air and medicaments are then mixed in the mixing zone.
3. As a result of the centrifugal force, the blended pulps are lead to the mineralization area. The air is in full contact with the coal particle and forms mineralized bubbles which are then equally distributed to groove wall and removed upward to the separation region. These bubbles then gather as a foam layer and are discharged by the scraping tool. Finally, clean coal foam is produced by this flotation machine.
4. Coal particles that are not mineralized will be remixed re-mineralized and re-separate through the recycle hole and the upper intake.
5. The left pulp that are not sucked by the impeller enters into the third tank after going through the process of first tank Thus, flotation machine runs in cycle and discharges ore pulp through the tailing box of the floatation machine.

Flotation-cell Features

The flotation machine consumes little amount of energy while at the same time maintaining a high air-absorption rate capacity. The machine is made up of individual cells which independently form a flotation separation loop without the need for any auxiliary equipment. They all are designed to carry out the following functions: air absorption, slurry absorption and flotation separation. Each of the cells is located horizontally to facilitate the easy change of flow. The mineral slurry circulates at a reasonable rate and the disposition of coarse sand is largely avoided. A self-control device is located on the surface of the mineral slurry facilitating easy adjustment of the level. There are two types of vanes found in the impeller: backward-inclined upper vanes and lower vanes, for upper and lower circulation of mineral slurry.
