بيت /Mineral Crushing And Flotation
Flotation. Flotation makes use of density separation, but in a special way. Chemicals are added to change the surface properties of the valuable minerals so that air bubbles can attach to them. The minerals are mixed with water to make a slurry, almost like a watery mud.

· Flotation is one of the most widely used separation methods in mineral processing field, especially popular in nonferrous metals processing. It mainly utilizes the differences in minerals surface properties of different minerals and float the hydrophobic minerals by injecting airs into the slurry while the hydrophilic minerals will remain as tailings.

The development of flotation opened new mineral resources for the mining industry and averted a twentiethcentury industrial crisis with the exhaustion of highgrade ore supplies. Disregarding earlier (and ineffective) specific gravity methods, inventors developed flotation, an ingenious process separating valuable minerals from complex ore bodies.
