Abstract: A cathode assembly for electrowinning metal in powder form, a system including the cathode assembly, and a method of using the assembly and system are disclosed. The cathode assembly includes a suspension element, a conductive element and a barrier element proximate the conductive element. The barrier element has a plurality of holes thereby reducing the effective active surface area of the cathode by shielding a portion of the cathode from participating in the electrowinning process. Metal is therefore deposited on or near the unshielded active surface in the form of metal powder. The assembly, system and method provide for improved metal powder formation. The system may be stationary or portable.

Abstract: The present disclosure provides systems and methods useful in suppressing the formation of metal oxides on an anode during electrowinning of a metal value. For example, a method is disclosed comprising electrowinning a metal value from a metal value-bearing electrolyte solution using an electrowinning system, the electrowinning system comprising an anode, and adding at least one of an acrylamide and a hydrocarbon with an acrylamide functional group to the metal value-bearing electrolyte solution for the suppression of metal oxide deposition on the surface of the anode.
