  • Development of Froth Flotation Mining-pedia

    Froth Flotation. At the beginning of the 20th century, the primitive froth flotation method appeared, which separates minerals according to the difference in physicochemical properties of the ore surface. At present, froth flotation process has become the most widely used ,and the process has developed relatively mature. The specific step is to

  • Froth flotation Wikipedia

    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.

  • Froth flotation ore dressing Britannica

    Froth flotation, separation of minerals differing little in density but greatly in wettability by surfactants that stabilize a froth formed on the surface of an agitated suspension of the minerals in water. See flotation. This article was most recently revised and updated by Erik Gregersen, Senior Editor.

  • Froth Flotation an overview ScienceDirect Topics

    Froth Flotation. Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34].

  • Flotation ore dressing Britannica

    Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to

  • Flotation Froth an overview ScienceDirect Topics

    Froth flotation is a physicochemical process that separates particles based on differences in surface wettability. Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles (Fig. 17). A chemical reagent, called a frother, is

  • The effect of froth depth on air recovery and flotation

    Oct 01, 2012· The froth depth was then changed, and the methodology was repeated until the new PAR was established. This was carried out at three froth depths in Cell 1. The air rate and froth depth were set to the positions that yielded the highest air recovery, and the same methodology was carried out in Cell 2, and subsequently Cell 3.

  • How Froth Flotation was Discovered and Developed

    The Minerals Separation company, owners of the froth patents, purchased the tailing-dumps on the Central mine, and, by arrangement, a plant was designed and erected by the Sulphide Corporation for their treatment. The plant is shown in cross-section in Fig. 23, and was designed on previous experience for the treatment of 2000 tons per week.
