The present invention is directed to a blast furnace and a method for operating a blast furnace which are able to reduce the CO2 production and reduce the amount of applied additives and heating material when compared to presently known metallurgical plants. This problem is solved by a process for metal production of metal ores comprising the following steps: reducing a metal ore, particularly a metal oxide; producing furnace gas containing CO2 in a blast furnace shaft; discharging said furnace gas from the blast furnace shaft; directing at least a portion of the furnace gas directly or indirectly into a CO2 converter and reducing the CO2 contained in the furnace gas into CO in the CO2 converter, directing at least a portion of the CO from the CO2 converter into the blast furnace shaft. Besides solving the above mentioned problem, the method also produces CO as a gaseous reduction agent which may be easily introduced into the blast furnace shaft.
