More Information
Summary:Methods and systems for producing iron from an iron-containing ore and removing impurities found in the iron-containing ore are disclosed. For example, a method for producing iron comprises providing a feedstock having an iron-containing ore and one or more impurities to a dissolution subsystem comprising a first electrochemical cell; producing an iron-rich solution, in the dissolution subsystem; treating the iron-rich solution to remove at least a portion of one or more impurities by raising a pH of the iron-rich solution from an initial pH to an adjusted pH thereby precipitating at least a portion of the one or more impurities in the treated iron-rich solution; delivering the treated iron-rich solution to an iron-plating subsystem having a second electrochemical cell; second electrochemically reducing at least a first portion of the transferred formed Fe
