Patent

CA 2009143

Proposed is a method of processing acidic solutions containing Fe and Zn, by liquid/liquid extraction with organic ion exchangers, wherein the first extraction step yields a first organic extract containing Fe3+, Fe2+ and Zn2+ and a depleted acidic solution, said first organic extract being used in a second extraction step to extract fresh solution, said second extraction step yielding a second organic extract containing Fe3+ and Zn2+ (and an acidic Fe2+ solution), and said second organic extract is stripped with acid to remove the Zn2+. In particular, the renewed extraction is carried out at a pH value which is changed as compared to the pH value of the first extraction.
