The effect of talc and muscovite on the froth stability of copper ore slurry was investigated using a froth column ().The froth stability was analysed using slurries of similar concentrations of the ore and talc/muscovite as used in the flotation tests.
The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless.
Sep 10, 2011· How flotation continues to, and needs to, evolve is perhaps no better illustrated than by the case of copper, the commodity where it finds its most important use, and produces the greatest annual tonnage.
Estimated Water Requirements for the Conventional Flotation of Copper Ores . By Donald I. Bleiwas . Introduction . This report provides a perspective on the amount of water used by a conventional copper
"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 ...
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.
Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
Results from lab scale flotation show that when process water was re-used copper and cobalt recovery from an oxidized ore decreased respectively with 25% and 30% at the rougher stage bringing lower grade concentrate as well.
