Recovery of molybdenum by solvent extraction from

2019-7-12  In this study, simple and a rapid solvent extraction method is investigated to recover Mo(VI) from simulated HLLW. The (NH4)6Mo7O24·4H2O dissolved in 3 M HNO3 was treated with ascorbic acid and KSCN to form orange red colored Mo(V)-SCN. Reduction of Mo(VI) was confirmed by cyclic voltammetry. The freshly formed complex was completely extracted to ethyl acetate layer.

Recovery of Co, Ni, and Li from solutions by solvent

The Li + extraction stoichiometry was studied by cultivating single crystals. Because cobalt, nickel, and lithium were recovered by single extraction, no other organic substances were required. This work provides a sustainable, environmentally friendly, and versatile method of recovering valuable metals from spent lithium batteries.
