Flotation machine technology can be used for a vast range of applications like Mineral separation, Industrial minerals for separating ferrous and non-ferrous metals. The Flotation machine has the advantages of large air-absorption capacity and low energy consumption. Every cell owns three functions: Air absorption, slurry absorption, and floatation separation, and the cells form a flotation separation loop by itself without any auxiliary equipment, and is allocated horizontally, which favors the change of flow. 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. The impeller has backward-inclined upper and lower vanes, which produce upper and lower circulation of mineral slurrry respectively.

At present, the volume of the ore dressing Flotation machine designed with this method can reach 150 m3, and the manufacturers are researching and producing even bigger flotation tank according to the production demands. The tank of this flotation machine is round equipped with bubble remover, bubble collector and ore discharging mouth as well as high-efficient level control system.

In the flotation separating process, the ore pulp flows through the flotation cell into the adjustable tailing down flow weir, and is absorbed on the impeller of the next cell, where it will get full mixing and inflation by the flotation machine again. The particles that are too heavy to flow into the down flow weir will be discharged from the sand discharging mouth in order to prevent the coarse particles from depositing inside the flotation cell. In the flotation separating process, the air amount through the ore pulp is determined by the circle rotary speed of the impeller of the flotation machine. In the practical production, we often make it as 7-10m/s. In addition, increasing the rotary rate of the impeller will increase the amount of the air;
