Flotation and flotation separator in the mineral processing plant

Flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles. The driving force for this attachment is the change in the surface free energy when the attachment occurs. These bubbles rise through the slurry and are collected from the surface. To enable these particles to attach, careful consideration of the chemistry of the pulp needs to be made. These considerations include the pH, Eh and the presence of flotation reagents. The pH is important as it changes the charge of the particles surface and the Eh effects the chemisorption of collectors on the surface of the particles.

The floatation machine is applicable for separating non-ferrous metal, black metal, noble metal, non-metal mineral, raw body and materials of chemical industry, which are subject to coarse separation, swept separation and flotation, so the useful ore are reclaimed.

Large air-absorption capacity and low energy consumption are the advantages of the floatation machine. Every cell owns three functions: air absorption, slurry absorption, and floatation separation, and the cells form a floatation 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.

In the mineral flotation process, flotation separator is the major and indispensable machine. High Effiencity Floatation Separator Machine is mainly used for selection of fine material from the cloth of gold inlay, silver, copper, iron, lead, zinc, molybdenum, nickel, aluminum and other Ores.

During the working process, the flotation separator is driven by the motor, the impeller revolves and produces a negative pressure, ample air is absorbed and mixed with the mineral slurry and additive. In this process, the mineral particle is bounded with foams, and floats up to the surface of mineral slurry, and forms the mineralized foam, then the useful foams are scraped by the squeegee installed in the flotation machine.
