  • Combination of threestage sinkfloat method and selective

    In flotation studies, the effects of wetting agent, frother, pH of solution and electrolyte on separation were determined. The selective flotation results showed that when using 500 mg l1 calcium lignosulfonate, 0.01 ppm MIBC, and 0.1 mg l1 CaCl2 at pH 11, PET could be separated from PVC.

  • FlotationMeaning of Flotation by Lexico

    Some of the most common separation techniques are leaching, flotation, filtration, chromatography, and centrifugal force. Colloidal phenomena are key in the separation of minerals from their ores by particle flotation. This is still a difficult market and it is obvious that the climate is different to the last flotation.
