Heinz Rennearch and in process development for REE recovery [.]. Antisolvent crystallization has the potential to recover REE from solution at high yields and with minimal waste. However, antisolvent addition generally results in uncontrolled primary nucleation and very small product crystals. A better approa

thus, a suitable chelating agent is required to accommodate the polarity difference between the solute and solvent during the extraction of metal ions with organometallic compounds. This study investigates four different organophosphorus ligands including triethyl phosphate (TEP), tri-n-butyl phosp

Roland Girtler of novel extractants for Pd(II) and Rh(III) chloridometalates. We have found that sulfide-diamide-type thiodiglycolamides (TDGAs) extract Pd(II) chloridometalates much faster than the conventional extractant di-.-hexyl sulfide (DHS). The TDGAs also show high stability against strongly acidic soluti
