Flotation Machine Main Components And Their Functions
The flotation machine is used for mineral processing. The ore slurry is doped, stirred, aerated, and mineralized through a preprocessor so that some of the mineral particles are selectively fixed on the bubbles; they float to the surface of the slurry and are scraped out to form products. It is retained in the slurry […]
