Abstract

A method for manufacturing iron metal in an apparatus through reduction of iron ore by an electrolysis reaction, the electrolysis reaction generating a gas, the apparatus including at least one casing including a gas permeable anode plate, a cathode plate, both facing each other and being separated by an electrolyte chamber, the cathode and the anode being connected to an electric power supply, the casing being provided with a circulator for circulating an electrolyte within the chamber and with a inlet to supply iron ore to the chamber, the pressure P of the electrolyte within the casing being maintained at a value of at least Plimit and the voltage V applied between the cathode and said anode being maintained at a value of at least Vlimit, the voltage V being always kept at a value strictly below the reduction curve of the electrolyte for the pressure P.
