  • Method for decontaminating soil containing resins
    Patent number: 5300258
    Abstract: A method for removing contaminated resin particles from soils. The method entrains the resin particles and fines from the soil, which, due to the difference in specific gravity between resin and soil particles, results in a significant disparity between particle size of the entrained resin and the entrained fines. This, in turn permits the fines to be screened from the resin and the larger soil particles, which have not been entrained, to settle out from the mixture.
