Abstract
Plastics are separated and recovered from mixtures containing plastics and other materials, by flotation in an aqueous dispersion, wherein the disperse phase comprises a substance such as for example calcium carbonate having an average mean particle size from about 1 micron to about 75 microns. The process is particularly useful for separating polyethylene and polyvinyl chloride from comminuted wire and cable scrap.
