flotation reagents mineral processing amp; metallurgythe function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the nonfloatable minerals. frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

froth flotation and gold extraction manhattan gold amp; silverjul 23, 20140183;32;most methods of waterbased gold extraction are dependent on golds lack of buoyancy to work. however, froth flotation uses a different property of gold to separate it from ore. froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).

Advantages of froth flotation metals

introduction to mineral processing chevron phillips chemicalin 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. sulfide and nonsulfide minerals as well as native metals are recovered by froth flotation.

froth flotation method jxsc machinethe froth flotation method is means separating minerals according to their different physical and chemical properties. according to classification, the flotability of gold and silver minerals is included in the first category of natural and nonferrous heavy metal sulfides, characterized by low surface wettability and easy flotation, which can be flotation by xanthate collectors.

flotation mineral processing amp; metallurgythe bubbles of air, sucked or blown into the pulp in the flotation machines, become coated with mineral and rise to the surface where they collect in the form of a mineralized froth. this primary concentrate, in which the bulk of the mineral is collected, continuously flows or is scraped over the lip of the machine into a collecting launder.
