Abstract

Disclosed are a method and corresponding apparatus in which mixture composed of two or more materials, one of which is foamable, has a gas added to it so as to form a foam fraction. The foam fraction is subsequently separated from the non foam fraction, thus separating the two materials from one another. The apparatus may feature a vessel 10 with a gas inlet port 12, headspace 18 for the foam, and conduit 16, to a first air lock 20 with a water wash, and a second air lock 22 with a solvent wash, and a pressure release valve 24. Also specified are a substantial number of different materials, mainly biological, which might be foam separated in the manner described.
