Abstract: 717,851. Extracting iron and other metals. WIBERG, F. M. Jan. 22, 1952 [Jan. 27, 1951], No. 1766/52. Classes 72 and 82 (1) In a process of reducing iron or other metal ores wherein a charge containing both ore and solid carbonaceous reducing agent is heated by combustion gases or combustion by air of gas passing through the charge, the individual pieces of carbonaceous reducing material, or bodies consisting of a mixture of fine grained ore and fine-grained carbonaceous material, are each surrounded with an outer layer of finegrained ore with or without other fine-grained non-combustible material (containing no or only a small amount of free carbon), which protects the material inside from combustion but which is sufficiently porous to allow gases formed during the reduction to escape. The non-combustible material may be lime, limestone or clay. and the layer may incorporate a binding agent. When the individual pieces of carbonaceous reducing material are coated, an intermediate layer of ore and carbonaceous material may be applied, and if the carbonaceous material is sulphorous, e.g. coke, an intermediate layer of sulphur-absorbing material may be applied or sulphur-absorbing material mixed with the carbonaceous material in the core or in the intermediate layer. In the form shown in Fig. 1, solid carbonaceous material in the lower part of the furnace 1 is burnt to CO by air and/or oxygen introduced 'at 2, and further air is introduced at 3 to burn the CO and heat the charge in the upper part of the furnace to the temperature at which the ore is reduced by the carbonaceous material in the charge. In the form shown in Fig 3, the charge in the lower part of the furnace 5 is heated electrically and gases formed by the reduction of the ore by the carbonaceous material. and passing out through the porous outer layers, are burnt by air introduced at 7 to heat the charge in the upper part to the final reduction temperature. In a further embodiment, CO formed in a separate apparatus is burnt with air in the furnace to reduce the charge to sponge iron. The outer layers may be applied to core bodies by rolling them in a drum containing the layer material, or by spraying a suspension of the material on to the cores, or by dipping the cores into such a suspension. Alloys may be formed by using cores of a mixture of solid carbonaceous material and one or more alloying elements in the form of metal or ore, and protective layers of fine-grained ore or oxide of some other alloying element. Pig iron powder can also be used for the cores, the carbon content of the pig iron serving as the carbonaceous reducing material. Specification 14612/11. [Class 82 (i)], . and German Specification 534,011 are referred to.
