PROCESS FOR EXTRACTING METAL FROM METAL ORES

摘要

The invention relates to a process for extracting metal from metal ores, especially iron from iron ore. According to the invention, the carbon and/or hydrocarbon-containing substances used to generate the reducing gas consist at least partly of plastic. When a metallurgical vertical kiln, especially a blast furnace (1), is used, the plastic is blown in large granular, fluidised form into the airstream in the hearth of the vertical kiln, with the particle size of the plastic primarily in the 1-10 mm range.
