Development of processes for metals recovery from special waste with production of nanoparticles

Mechanical and hydrometallurgical routes have been developed aiming to recover metals from spent batteries such as lithium ion, primary lithium and nickel metal hydride batteries. Moreover nanoparticles of manganese carbonate were synthesized by microemulsione mediated route with the future goal of performing a production of nanoparticles downstream of a hydrometaluurgical process for batteries valorization.
