Abstract
This invention relates to a system and method for producing a metal powder product using either conventional electrowinning or alternative anode reaction chemistries 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, direct electrowinning, or alternative anode reaction chemistries.
