1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral water slurry The particlesOct 16 2017 Column flotation devices were re introduced for mineral processing by Boutin and Wheeler in Canada in 1967 when wash water addition to the froth was used to eliminate entrainment of hydrophilic materials to the float product By the late 1980s column flotation had become a proven industrial technology in the mineral industry

Cassiterite Flotation Mineral Processing & Metallurgy

Synopsis This paper presents both the fundamentals of sulphide mineral flotation and the practical aspects of sulphide ore flotation The fundamental aspects of the flotation of sulphide minerals both in the absence and presence of thiol collectors are discussed in relation to their crystal structure surface chemistry and electrochemical characteristicsThe nominal size range for cassiterite flotation is between 2 and 100 microns The top size is variable depending upon the liberation of the cassiterite particles Cassiterite grains coarser than 100 microns are difficult to float whilst grains finer than 2 microns give selectivity problems Hence the feed for cassiterite flotation should be reduced to 95 minus 100 microns and then deslimed
