Abstract: Methods and systems for producing are disclosed. A method for producing iron, for example, comprises: providing an iron-containing ore to a dissolution subsystem comprising a first electrochemical cell; wherein the first anolyte has a different composition than the first catholyte; dissolving at least a portion of the iron-containing ore using an acid to form an acidic iron-salt solution having dissolved first Fe3+ ions; providing at least a portion of the acidic iron-salt solution to the first cathodic chamber; first electrochemically reducing said first Fe3+ ions in the first catholyte to form Fe2+ ions; transferring the formed Fe2+ ions from the dissolution subsystem to an iron-plating subsystem having a second electrochemical cell; second electrochemically reducing a first portion of the transferred formed Fe2+ ions to Fe metal at a second cathode of the second electrochemical cell; and removing the Fe metal.

Abstract: Methods and systems for producing iron from an iron-containing ore are disclosed. For example, a method for producing iron comprises: providing an iron-containing ore to a dissolution subsystem comprising a first electrochemical cell and a dissolution tank; dissolving the iron-containing ore to form an acidic iron-salt solution; reducing Fe3+ ions to form Fe2+ ions and electrochemically generating protons in the first electrochemical cell; circulating solution between the dissolution tank and the first electrochemical cell; transferring formed Fe2+ ions from the dissolution subsystem to an iron-plating subsystem having a second electrochemical cell; second electrochemically reducing a first portion of the transferred formed Fe2+ ions to Fe metal at a second cathode of the second electrochemical cell; and removing the Fe metal. The methods and systems optionally include removing one or more impurities found in the feedstock.
