  • Flotation Froth - an overview ScienceDirect Topics

    For example, froth flotation is a technique commonly used in the mining industry. In this technique, particles of interest are physically separated from a liquid phase as a result of differences in the ability of air bubbles to selectively adhere to the surface of the particles, based upon their hydrophobicity.

  • Frothers Froth Flotation ArrMaz

    Frothers Froth Flotation. The importance of frothers in mineral flotation is widely acknowledged in the mining industry. Frothers perform the following key functions in the froth flotation process: Reduce surface tension of the liquid-gas interface to enable froth formation; Hinder coalescence in order to stabilize bubble size

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper- and le

    Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
