Abstract

This invention relates to a system and method for producing a metal powder product using conventional electrowinning chemistry (i.e., oxygen evolution at an anode) in a flow-through electrowinning cell. The present invention enables the production of high quality metal powders, including copper powder, from metal-containing solutions using conventional electrowinning processes and/or direct electrowinning.
