Abstract
This invention relates to an apparatus for producing a metal powder product using either conventional electrowinning or alternative anode reaction chemistries in a flow-through electrowinning cell. A new design for a flow-through electrowinning cell that employs both flow-through anodes and flow-through cathodes is described. 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 chemistry.
