Abstract: A process for electrowinning a metal can include the steps of: a) conveying an anolyte material and a metal chemical feedstock material along an anolyte flow path within an anolyte chamber; b) conveying catholyte material along a catholyte flow path within a catholyte chamber that has a cathode; c) applying an activation electric potential between the anode and a cathode that is sufficient to electrolyze and liberate metal ions from the metal chemical feedstock material in the anolyte chamber, thereby causing a flux of metal ions to migrate through a porous membrane from the anolyte chamber to the catholyte chamber and a metal product to be formed in the catholyte chamber; and while applying the activation electric potential, extracting a feedstock-depleted anolyte material from the anolyte chamber; and extracting an outlet material comprising the catholyte material and the metal product from the catholyte chamber via a catholyte outlet.

Abstract: An electrorefining process for refining relatively purer lithium metal from a lithium-alloy feedstock material using a three-layer electrorefining apparatus can include a) providing an anode layer comprising a molten, lithium-alloy feedstock material that includes a combination of lithium metal having a first purity and a carrier material; b) providing an electrolyte layer comprising a molten salt electrolyte material; c) providing a product layer comprising molten lithium metal having a second purity that is greater than the first purity above the electrolyte layer; and d) applying an activation electric potential that is sufficient to electrolyze the lithium-alloy feedstock material between an anode layer and the product layer that is electrically isolated from the anode layer, whereby lithium metal is liberated from the lithium-alloy feedstock material, migrates through the electrolyte layer and collects in the product layer.

Abstract: A process for electrowinning a metal using a flow-through electrowinning apparatus can include the steps of: a) conveying an anolyte material and a metal chemical feedstock material along an anolyte flow path within an anolyte chamber; b) conveying catholyte material along a catholyte flow path within a catholyte chamber that has a cathode; c) applying an activation electric potential between the anode and a cathode that is sufficient to electrolyze and liberate metal ions from the metal chemical feedstock material in the anolyte chamber, thereby causing a flux of metal ions to migrate through a porous membrane from the anolyte chamber to the catholyte chamber and a metal product to be formed in the catholyte chamber; and while applying the activation electric potential, extracting a feedstock-depleted anolyte material from the anolyte chamber; and extracting an outlet material comprising the catholyte material and the metal product from the catholyte chamber via a catholyte outlet.
