  • Processes for the selective separation of iron and aluminium
    Patent number: 10087501
    Abstract: This disclosure relates to a process for selectively extracting Fe(III) ions from an aqueous feedstock containing Fe(III) ions and non-ferric ions. The process comprises contacting the feedstock with an organic phase comprising a phosphonium salt or ammonium salt ionic liquid under liquid-liquid extraction conditions for a time sufficient to allow transfer of at least some of the Fe(III) ions from the feedstock to the organic phase to provide an Fe(III) ion laden organic phase and an Fe(III) depleted feedstock, and separating the Fe(III) ion laden organic phase from the Fe(III) depleted feedstock.
    Type: Grant
    Filed: August 7, 2015
    Date of Patent: October 2, 2018
    Assignees: University of South Australia, Shanxi Ruienze Technology Co., Ltd., Shanxi University

  • EXTRACTION OF GOLD
    Publication number: 20140363356
    Abstract: Disclosed is a process for extracting gold ions from an aqueous phase containing gold ions. The process comprises contacting the aqueous phase with an extractant phase consisting of or comprising an ionic liquid (IL) under liquid-liquid extraction conditions for a time sufficient to allow transfer of at least some of the gold ions from the aqueous phase to the extractant phase; and separating the extractant phase from the aqueous phase.

  • EXTRACTION OF METALS
    Publication number: 20140299543
    Abstract: A process for extracting a target metal ion from an aqueous feedstock containing, inter alia, the target metal ion. The process comprises providing said feedstock and contacting the feedstock with a room temperature ionic liquid (RTIL) that is substantially free of an extraneous organic extractant under liquid-liquid extraction conditions for a time sufficient to allow transfer of at least some of the target metal ions from the feedstock to the RTIL. The RTIL is then separated from the feedstock and the target metal ions are recovered from the RTIL.
