As a Flotation Equipment technology and equipment supplier, Zhejiang golden machinery factory proposes solution to this problem. In the case of fine and coarse fractions, there are different flotation technologies that are designed to achieve optimum recovery and grade for each size class-one type of flotation machine does not fit all applications.

Flotation, or more specifically froth flotation, is a physicochemical method of concentrating fine minerals and coal. The process involves chemical treatment of a pulp to create conditions favorable for the attachment of particles to air bubbles. Some particles are not readily wetted by water (hydrophobic), while others are readily wetted by water (hydrophilic).

By the addition of chemicals these proper­ties can be enhanced. Air bubbles are created by the rapid motion of the agitator mechanism which draws air down the hollow shaft and disperses the air into the pulp. The air bubbles carry the hydrophobic particles to the surface of the pulp and form a stabilized froth which is skimmed off while the hydrophilic particles remain submerged in the pulp.
