Embodiment 1
[0021] Embodiment 1——the reduction treatment method of hematite:
[0022] The equipment adopted in the present embodiment to the reduction of metal ore is as figure 1 As shown, there is a reduction treatment furnace for metal ores. There is a feed hopper 1 at the upper end of the reduction treatment furnace for metal ores. There is a flue gas outlet between the feed hopper 1 and the furnace shell 2 of the reduction treatment furnace for metal ores. The upper end inlet of the feed hopper 1 is the metal ore inlet of the metal ore to be reduced in the reduction treatment furnace of the metal ore. The lower end of the reduction treatment furnace of the metal ore is connected with a screw conveyor 16 through the collecting hopper part 8, and the metal ore of the screw conveyor 16 is The ore outlet is the metal ore outlet of the metal ore reduction treatment furnace, and the metal ore after the reduction reaction is exported out of the furnace from here.
