Abstract
The invention relates to a method for processing slags of non-ferrous metallurgy,containingiron and valuable metals,to produce clean slagthatis free of detrimental substances and valuable metals and suitable as it isfor use as a raw material or construction material. Slag is reduced in a reduction furnace (18) with the help of reducing agents (19) so far that at least 5% of the iron ofthe slag is reduced into metal. At the same time, some of the valuable metals, such as zinc, lead, arsenic and cadmium, vaporize. The contents ofthe reduction furnace (18) arecontinuously mixedto prevent separation of a metallic phase from the slag. The generated slag-metal mixture (21) is tapped off from the reduction furnace (18), cooled, crushed and ground to a finer size. Finally, a metal fraction (26) is separated from a clean slag (25).
