摘要: The present invention provides a method for selectively separating co-mingled materials of different densities by selective density flotation the in fluid vicinity its critical point. extermely high compressibility point allows continuous variations over maximum range to be accomplished using minimal changes temperature and pressure. Materials exhibiting similar can thus separated adjusting between two materials.
