发明名称 Method for producing metal from metal ores
摘要 The invention relates to a method for producing metal from metal ores, in particular crude iron from iron ore. The point of the invention is that the carbon- and/or hydrocarbon-containing substances used for generating a reducing gas consist at least partially of plastic. When a metallurgical shaft furnace is used, in particular a blast furnace (1), the plastic is blown in a coarse-grained fluidised form into the blast stream in the hearth of the shaft furnance, the particle size of the plastic being predominantly in the range of 1-10 mm. <IMAGE>
