Flotation process maximizes the enrichment of gold into sulfide minerals. The tailings can be directly discharged. Process description In the flotation process of the major steps that must be done include the process destruction of rock minerals, milling, flotation, drying, and smelting. 1. Crushing and Grinding stage 2.
However, this process is based upon density alone and should not be confused with the process of froth flotation. Thus, the process of froth flotation is not solely dependent upon the density of the material it is also dependent upon its hydrophobic nature. For example, froth flotation is a technique commonly used in the mining industry.

When flotation machine work, the feed tube feed the slurry to the center of coverplate, the impeller rotating centrifugal force generated the pulp out, at the same time form a negative pressure between the impeller and the cover plate, and the intake pipe automatically inhale the outside air.
The slurry-gas mixed flow is moved in a tangential direction by the impeller, and then converted into radial movement by the action of the stator, and is evenly distributed in the flotation cell. The mineralized bubbles rise to the froth layer and are scraped out unilaterally or bilaterally to form froth products.
