Abstract

An electrochemical reactor, including a channel for containing and directing flow of an electrolyte stream, wherein the electrolyte stream includes an electrolyte and an iron-containing feedstock; an anode and a cathode positioned in contact with the channel; and a source of a magnetic field positioned in proximity to the cathode, wherein the electrochemical reactor is configured to electrochemically reduce at least a portion of the iron-containing feedstock to iron metal at a surface of the cathode and in a magnetic field of the source, and wherein the at least a portion of the iron-containing feedstock is electrochemically reduced to the iron metal at a current efficiency of at least 0.75, wherein the current efficiency is a ratio of charge used for the reduction of the iron-containing feedstock to a total charge provided to the cathode.
