Mar 11, 2016 Flotation Principles. Flotation, in its latest phase, is a process of concentrating ores by frothing. When crushed ore, previously mixed with water and a relatively minute addition of oil, is agitated violently in the presence of air, a froth is formed. This froth, rising to the surface of the liquid mixture, is laden with sulphides or other ...
The flotation method is based on the difference in the physical and chemical properties of the mineral surface, processed by the flotation agent, and the mineral is selectively attached to the bubbles to achieve the purpose of separation. ... etc., is mainly treated by flotation; some ferrous metals, rare metals, and some non-metallic ores ...
Flotation is a combination of chemical, physiochemical, and physical phenomena that govern the three-phase flotation system. The mineral–water, mineral–air and water–air interfaces are considered to possess a surface energy that plays a decisive role in most of the aspects of the flotation phenomenon.
