Abstract

This study investigates the capability of electrochemical techniques for the production of metal oxide materials from hydrometallurgical process solutions by deposition on an electrode surface. Morphology and deposited material composition are characterized by different techniques including SEM-EDX and cyclic voltammetry. Additionally, the influence of potential, temperature, manganese concentration, and pH on the process are examined.
