ABSTRACT:
An inexpensive electrowinning electrode has a cathode that is a porous form made from conductive filaments, and an anode. The electrowinning process dissolves a contaminated metal stream into an electrolyte to form a solution flow of dissolve metal and contaminants. Next, the solution is oxidized. Then, the dissolved metals in the solution are plated onto the porous cathode.
