froth floatation method

CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION TO ...

flotation has now expanded to include oxides, such as hematite and cassiterite, oxidised minerals, such as malachite and cerussite, and non-metallic ores, such as fluorite, phosphates, and fine coal. The flotation method of concentration, used extensively for other metal ores, has only recently been utilized for hematite iron ores.

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 ...
