froth flotation process ppt

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 Flotation-Definition Froth flotationis a process used for separating hydrophobic [having little or no affinity for water] materials from hydrophilic[having a strong …

PowerPoint Presentation: INTRODUCTION FLOTATION is a physico-chemical separation process that utilizes the difference in the surface properties of the valuable and gangue minerals. FROTH FLOTATION involvesthree different phases- solid (fine ore powder),liquid (water) and froth.

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.

Xanthate, as theflotationcollector with strong collection effect, is mainly used to enhance the hydrophobicity of the mineral surface to meet the requirements offlotation.Xanthate is commonly used in theflotation processof sulfide minerals. Xanthate is a combination of alcohol, sodium hydroxide and carbon dioxide, which is an anionic collector. . It is light yellow, soluble in water and ...

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.
