  • Flotation Mineral Processing & Metallurgy

    The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generallyOre Concentration by Froth Flotation The waste material that comes out of the bottom of the tanks at the tail end of this process is called "tailings" It is nothing more than groundup rock with the copper minerals removed MiddlingsFlotation Concentration Elmhurst Universityflotation gravitation concentration process Froth Flotation Process Another method of concentration of ores is the Froth Flotation Method This is the process for concentration of primarily sulphide ores It has the advantage over gravity separation because it can collect even the extremely fine particles of mineralsncentration process flotation
