r (Cu), nickel (Ni), cobalt (Co), lead (Pb) and zinc (Zn) from waste printed circuit boards (WPCBs) via iodine-iodide leaching and precipitation. The behaviours of dissolution and precipitation of precious and base metals during iodine-iodide leaching and precipitation processes were discussed. Sodi

Ingeborg Hellingearch 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
