Abstract

An apparatus ( 1 ) for the production of iron metal through reduction of iron ore by an electrolysis reaction the apparatus including a casing ( 4 ) including successively a terminal anode plate ( 2 ) at a first end of the casing ( 4 ), such anode being connected to a source of electric power, at least one bipolar electrode ( 11 ) including successively a cathode plate ( 3 ), a metallic plate ( 12 ), a gas recovery part ( 8 ) and a gas permeable anode plate ( 2 ) and a terminal cathode plate ( 3 ) at the other end of said casing ( 4 ), such cathode being connected to the source of electric power.

First claim

1 - 6 . (canceled)

7 . An apparatus for the production of iron metal through reduction of iron ore by an electrolysis reaction, the electrolysis reaction generating a gas, the apparatus comprising:
a casing including successively:
a terminal gas-permeable anode plate at a first end of the casing, the anode plate being connected to a source of electric power and a gas recovery part extending along an upper part of the anode plate,
at least one bipolar electrode including successively a cathode plate, a metallic plate, a gas recovery part and a gas-permeable anode plate,
a terminal cathode plate at the other end of the casing, the terminal cathode plate being connected to the source of electric power,
a gap being maintained between said terminal anode plate and the cathode plate of the bipolar plate, the gap forming an electrolyte chamber,
a further gap being maintained between the terminal cathode plate and the anode plate of the bipolar plate, the further gap forming a further electrolyte chamber,
the casing circulating an electrolyte within the electrolyte chambers and having a supply to supply iron ore to the electrolyte chamber and further electrolytic chamber and a gas outlet in fluidic connection with the electrolyte chamber and further electrolytic chamber.

8 . The apparatus as recited in claim 7 wherein the casing includes a plurality of bipolar electrodes extending successively between the terminal anode plate and the terminal cathode plate, a gap being maintained between each bipolar electrode to define a respective electrolyte chamber.

9 . The apparatus as recited in claim 7 wherein the terminal anode plate and the terminal cathode plate are part of bipolar electrodes.

10 . The apparatus as recited in claim 9 wherein the bipolar electrodes are held together with connectors.

11 . The apparatus as recited in claim 7 wherein the terminal cathode plate and the cathode plate of the bipolar electrode are made of graphite.

12 . The apparatus as recited in claim 7 wherein the source of electric power is supplied by renewable energy.
