  • NEW APPLICATIONS FOR FROTH FLOTATION PROCESSES
    Publication number: 20090095660
    Abstract: A process is described for the separation of fluorinated plastic particles from a mixture of solid particles of similar specific gravity. The process comprises mixing the particles with water, adding air to create bubbles, and generating two or more product streams, one of which floats and the other which sinks. The floating stream is enriched in fluoropolymer particles. Per pass yield and selectivity of fluorinated plastics are enhanced by the addition of a carboxylic acid to the froth flotation medium.
