  • Separation and recovery of thermoplastics by froth floatation

    This paper describes efforts by Argonne National Laboratory to develop a froth flotation process for separating and recovering plastics from mixed plastics waste streams generated from shredding obsolete appliances and automobiles. A process for recovering and separating equivalent-density ABS and HIPS from obsolete appliances was developed and pilot-tested with a through-put of 1 250 lbs/hr.

    Jun 01 1999 · Argonne has patented a froth-flotation process for separation of ABS and HIPS which is the middling fraction left over after the lighter and heavier fractions have been removed by the sink/float method. The froth flotation process is capable of separating ABS and HIPS from the mixture in purities greater than 98 percent according to Argonne.

  • A review of froth flotation controlScienceDirect

    Sep 14 2011 · It is common in industry for operators to control and regulate a flotation plant by visual inspection of the froth surface. Indeed an understanding of processes occurring within the froth phase is central to understanding the overall behaviour of flotation systems ( Glembotskii 1972 Cutting et al. 1986 McKee 1991 Mathe et al. 1998 ).

    Flotation is a physico-chemical separation process that utilises the difference in surface properties of the valuable minerals and the unwanted gangue minerals. The theory of froth flotation is complex involving three phases (solids water and froth) with many subprocesses and interactions and is not completely understood. (Wills 2005)
