Oct 01, 2003 The flotation behavior of the oxidized, high-chromium PGE ores is different from that of the high chromium unoxidized ore. Specifically, the flotation activity of the gangue and chromium is more pronounced, and the oxidized PGE-bearing minerals are not readily floatable. Flotation studies on this ore were concentrated on examining the ...

I claim 1. An improved of oxidic of beneficiating ores and minerals selected from the group of oxide ores and minerals or iron, chromium, cerium, yttrium, antimony, and phosphorous by froth flotation process to produce a froth concentrate of desired metal value which improvement comprises effecting the froth flotation of the ore by treating the comminuted ore of the mineral slurry of ...
Apr 17, 2019 Froth flotation is the use of the physical and chemical properties of the surface of the ore, the use of chemical separation of useful ore. In the process of froth flotation, useful minerals are separated by floating them in the foams, and the way of keeping gangue minerals in the pulp is called positive flotation, while the way of floating gangue minerals in the foam is called reverse flotation.
Jan 20, 2021 The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated well ground mineralsmetals and makingplaying on making them hydrophobic water-repel individually to carefully separate them from one another and the slurry they are in.
