The flotation machine is considered as the common device in the ore beneficiation process. In the first place, we should learn about the working principle of the flotation machine. The impellor of the flotation machine is driven to rotate by the motor triangle belt and forms a negative pressure by the centrifugal effect. On the one hand, the machine sucks enough air to mix with the ore pulp; on the other hand, the ore pulp will be blended with the mineral agent. The materials will float to the surface of the ore pulp and will become the mineralized foam. Then we should adjust the height of the shutter to control the liquid level and finally remove the foam by the scrape blade.

The flotation machine is often used to separate the ferrous and non-ferrous metals and other non-metal materials like calcium fluorite and talc. There are many elements that are easy to ignore during the operation of the equipment.

1. The surface action between the air and minerals is in alternative and the main factor that has much effect on the mineral surface is oxygen.

2. The oxygen has great influence on the hydrophobic property of the sulfide ores. If the action takes quite a long time, it will make the mineral surface become hydrophilic. When the condition is just right for the air adsorption, it will provide good environment for the flotation process without adding flotation agent such as the dry coal dust.

3. When the minerals are broken with new surfaces, they will perform hydration action with water. When the air is absorbed on the surface of the minerals, the hydration effect will be reduced.

Our experts remind customers of the above factors to pay attention to and through useful measures we will improve the flotation efficiency and reduce the flotation cost.
