froth flotation process ppt

Floatation - LinkedIn SlideShare

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 process powerpoint

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. The process of separation of mineral includes three important mechanisms : 1.

Flotation Process- an overview | ScienceDirect Topics

Thefroth flotation processis more than a century old and was developed over a long period of time [8]. It takes advantage of the surface chemistry of fine particles—if one particle’s surface is hydrophobic and another is hydrophilic, upon generation of air bubbles, the hydrophobic particles tend to attach to the air bubbles and float ...

Flotation Froth- an overview | ScienceDirect Topics

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.
