摘要： problem according to the invention, compared to the metallurgical plant
currently being used, CO blast furnace and exhaust, and with additives suitable for
reducing the amount of heating fuel it is to create a method of operating a blast furnace.This object is achieved by the processing method of the metal ores. Processing method of the metal ore, metal ore, in particular reducing the metal oxide to produce a furnace top gas containing CO in the blast furnace shaft, discharging the top gas from the blast
furnace shaft, furnace at least a portion directly or indirectly CO led to the converter, CO CO to produce CO by reducing, at least a first portion of the CO from the CO converter consists of directing the blast furnace shaft. In addition to the solution of the problems described above, CO as gaseous reducing substance can be easily supplied to the blast furnace shaft, is generated by the process. Blast furnace for extracting metals operated by the process, a blast furnace shaft and at least one CO inlet and first top gas outlet, CO CO converter gas inlet and CO converter inlet and the have CO was suitable for reduction in CO CO and a converter. Furnace top gas outlet are directly or indirectly connected to the CO converter gas inlet, CO converter, CO comprising at least a first 1CO outlet for discharging a first portion of the CO produced by the converter, at least the 1CO outlet is directly or indirectly connected to the blast furnace shaft.
