The behaviours of dissolution and precipitation of precious and base metals during iodine-iodide leaching and precipitation processes were discussed. Sodi

It can be answered by using solid phase extraction, applying highly selective nanostructured adsorbents. The latter are bearing organic ligands with high specific affinity to particular

This paper describes a hydrometallurgical process for the recovery of rare earth elements from hard disk drives using HCl as a re-usable extraction medium. The mixture was selectively le

However, antisolvent addition generally results in uncontrolled primary nucleation and very small product crystals. A better approa
