Abstract

The quality of recycled magnesium from chips depends strongly on their exposure to inorganic and organic impurities that are added during the production processes. Different kinds of magnesium chips from these processes were analyzed by several methods. In addition, the accuracy and effectiveness of the methods are discussed. The results show that the chips belong either to the AZ91, AZ31, AM50/60, or AJ62 alloy. Some kinds of chips show deviations from the above-mentioned normations. Different impurities result mainly from transition metals and lime. The water and oil content does not exceed 25%, and the chip size is not more than 4 mm in the diameter. The sieve analysis shows good results for oily and wet chips. The determination of oil and water shows better results for the application of a Soxhlet compared with the addition of lime and vacuum distillation. The most accurate values for the determination of water and oil are obtained by drying at 110°C (for water) and washing with acetone (for oil) by hand.
