China Flotation Machine for Fine Minerals Recovery - Suppliers and Factory for Ore Beneficiation Equipment
Description
Flotation machine is an equipment for ore beneficiation through separating hydrophobic materials from hydrophilic. It is widely used in recovery for fine minerals of ferrous metal, precious metal, rare metal, nonferrous metal, non-metallic minerals and so on. The flotation machine is mainly composed of slurry tank, agitation device, air charging device, discharge mineralized bubble device, motor. Ascend produces a wide variety of flotation machines, such as mechanical flotation machine, air charging agitation flotation machine and etc. among which mechanical agitation flotation machine is commonly used.
Working principle
When the flotation machine works, the motor drives the impeller to revolve, producing the centrifugal effect and negative pressure. The grinding ore, water and necessary chemicals are mixed into slurry through the mixing tank. Then it is injected into the slurry tank to start mixing. On the one hand, ample air is absorbed and mixed with mineral slurry to form a large number of bubbles. On the other hand, the mixed mineral slurry is mingled with additive. Meanwhile, the foams get thinner and bounded with minerals. Some mineral particles which are not easy to be wet are generally called hydrophobic mineral particles. They are attached to the foams. Then foams float up to the surface of mineral slurry and become the mineralized foams. Others, which are easy to be wet, are generally called hydrophilic mineral particles. Instead of adhering to the bubble, they will stay in the pulp. At last, it will discharge the mineralized bubble containing specific minerals.
The liquid surface can be adjusted with the height of adjustment flashboard, so that the useful foams are scraped with squeegee.

Frequently Asked Questions
A flotation machine is used for ore beneficiation by separating hydrophobic materials from hydrophilic ones. It is widely applied in the recovery of fine minerals, including precious metals, ferrous metals, rare metals, nonferrous metals, and non-metallic minerals.
The machine is primarily composed of a slurry tank, an agitation device, an air charging device, a mineralized bubble discharge device, and a driving motor.
The motor rotates the impeller to generate centrifugal force and negative pressure. Air is mixed with the chemical-treated mineral slurry to create bubbles. Hydrophobic mineral particles attach to these bubbles and float to the surface as mineralized foam, while hydrophilic particles remain in the pulp.
Ascend produces various types of flotation machines, including mechanical flotation machines and air charging agitation flotation machines. The mechanical agitation flotation machine is the most commonly utilized model.
The liquid surface level is controlled by adjusting the height of the adjustment flashboard. This allows the target mineralized foam to be efficiently scraped off using a squeegee.
The processing capacity varies by model, starting from 0.2-0.4 t/h for the smallest SF0.37 model, up to 4.0-8.0 t/h for the larger SF8.0 model.
