(54)    Title

Apparatus for producing metal powder by electrowinning

(57)    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 electro winning 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
