Abstract: Production of high purity iron powder employs high efficiency low temperature electrolysis resulting in a process requiring substantially less energy with no CO2 gas and has high energy reduction. Configurations provide a renewable electricity supply that is environmental benign with low energy consumption. A hematite (Fe2O3), carbon and highly concentrated NaOH combine to form an electronically and ionically conductive suspension for iron production. The suspension is flowable which can also be applied to a flow electrolysis system. High purity iron powder is produced at the cathode side while the anode side can produce O2 gas as a byproduct.
