The demand for magnesium alloys that has steadily been growing in the automobile and electrical industries for some years, has also led to increasing quantities of used magnesium scrap. Processing of the secondary material that becomes available is not only an ecological necessity and an economic potential, but also constitutes a metallurgical challenge. Magnesium components that have reached the end of their life cycle but are contaminated by association with other materials such as steel, copper or nickel, require new melt-metallurgical refining methods. The aim of a research project by the company non ferrum Metallpulver is therefore to reduce the content of contaminant element in magnesium melts by pyrometallurgical refining, by forming intermetallic compounds.
