Abstract

221,780. Australian Minerals Recovery Co., Ltd., (Assignees of Copper Separation, Ltd.). Sept. 15, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Extracting. - Sponge iron is produced by heating a mixture of iron oxide and carbonaceous material to about 900‹ C. in a rotary furnace 10 mounted in brickwork so that it is externally heated. The furnace 10 is mounted on hollow trunnions 11, 12 supported on roller bearings 13, 14. A tube 16, provided with a screw conveyer mounted on a shaft 18, passes through the trunnions 11, 12, and is provided with a launder 17 opening into the furnace 10. Tubes or conduits 19, 20 are fitted at each end of the tube 16 and are provided with valves for opening and closing the passages therein. In operation, the tube 16 is turned so that the tube 19 is facing upward and the valve therein opened. The mixture of ore and carbonaceous material is fed therein and the shaft 18 rotated to feed the mixture through the launder 17 into the furnace. 10. When the charging is complete, the valve in the tube 19 is closed, and the furnace 10 rotated continuously whilst being heated to the desired temperature. When the reaction has proceeded for the deter. mined period, the shaft 18 is rotated and the valve in the tube opened, the reduced material falling into the launder 17 and then being conveyed to the tube 20, the product issuing therefrom being suitably cooled. The inside of the furnace 10 is provided with projecting rabbles which are inclined at such an angle as to shower effectively the charge during rotation.
