Froth Flotation Process - Mineral Processing & Metallurgy

"The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories of hydrophobicity that are increased by ...
