  • Patent number: 4612114
    Abstract: A method and apparatus for separating discrete solid fractions from dispersion in a dense liquid medium wherein the suspended materials are subjected to settling to produce a low density fraction floating on the surface, a middlings fraction suspended in the liquid medium, and a high density fraction which sinks to the bottom. The high density fraction is lifted off in a region of the dense medium in which the surface level of the dense medium is substantially free from particles of the floating low density fraction.
