Summary

The increasing application of magnesium alloys in automotive, aerospace and other industries leads to the loss of a large amount of magnesium during production processes. It has become important in the magnesium industry to minimise the environmental impact of waste products and to utilise an economical source of secondary magnesium. It is shown that in typical magnesium die-casting operations only about 50 % of the metal input ends up as a finished product. The remaining 50 % goes to scrap. Finely divided waste in the form of machining swarf is seen as an acute problem in case of fire and it is urgent to convert this to a less potentially incendiary form.
