Electrowinning and Smelting - Resource Book
The process of electrowinning simply involves passing an electric current through the electrolyte (eluate). Electrons (electricity) pass from the cathode (negative electrode), through the solution and into the anode (positive electrode), completing the electrical circuit. The current causes the gold to plate out onto the steel wool cathodes. Upon the completion of an electrowinning batch, the ...
