  • FLOTATION

    Flotation is a process in LiquidSolid Separation technology whereby solids in suspension are recovered by their attachment to gas (usually air) bubbles, usually with objective of removing the solids from the liquid The particles most effectively removed are in the size range from 10 to 200 μm The particlebubble aggregates that are formed have a density less than the suspension itself14/04/2016· Recommendations for Copper Zinc Separation by Flotation On ores of this type it is very essential to carry out a comprehensive test program on representative samples taken from various zones of the mining operation Samples should be shipped in sealed containers to retain the original moisture content and soluble salts and tested without delay This minimizes the effects of surface oxidationChalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation01/02/2004· Flotation was originally developed for ore separation about a century ago Early research studies on plastics flotation were concerned with testing surfactants known from ore flotation While searching for suitable wetting agents has been the principal research subject in this field, it became clear later that other surface treatments can also be utilisedSeparation of waste plastics by froth flotation––a review
