Froth Flotation Principles

Feb 26, 2017· Froth Flotation Method for Sulphide Ores. The floatation process at present finds its greatest scope in recovery from ores whose predominant values are associated both chemically and physically with sulphides. The major proportion of the present day worlds base metal production is procured by the flotation process. Since its inception flotation has been responsible for a vast improvement in the metallurgy of sulphide ores.

Mineral processing

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.

Froth flotation

Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven workplace applications, especially at Broken Hill, Australia, that brought the technological innovation known as froth flotation. During the early 20th century, it dramatically revoluti

Crushing, Grinding and Concentration of the Ore

Apr 02, 2020· This method has been used for the concentration of sulphide ores, such as galena (PbS), zinc blende (ZnS), copper pyrites (CuFeS 2), etc. The sulphide ore particles are preferentially wetted by oil and gangue particles by water. a) In this method, the powdered ore is mixed with water to form a suspension in a tank.
