froth flotation process ppt

Jun 16, 2013· Froth FloatationPresented By:Gulfam Hussain 2.Introduction Floatation is an extractive process where variousminerals can be selectively extracted. Flotation is a selective process and can be used toachieve specific separations from complex ores. For example, in poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cuand Zn.

Jan 30, 2015·Oil and froth float on the surface along with the sulphide ore. The gangue particles being insoluble in oil remain at the bottom of the water tank. The froth is removed and allowed to settle down. This is called the froth-floating process. This process is used for sulphide ores of Cu, Pb and Zn 10 11.

Froth flotationis aprocessthat selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the wordflotationis also used in the literature to describe theprocessin density separation in which lighter microplastics float to the surface of a salt solution.

FlotationFrothers What is the Function of Frothers. The function of frothers inflotationis that of building thefrothwhich serves as the buoyant medium in the separation of the floatable from the non-floatable 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.
