  • Patent number: 4065299
    Abstract: A magnesium reclamation process whereby magnesium and magnesium alloy fines, chips and scraps may be recovered and remelted for reuse. The method is comprised of the steps of pelletizing the magnesium by first compacting the magnesium with a low pressure press so as to initially expel the majority of the air, followed by a high pressure press under a controlled environment to form a compact pellet. The pellets are then melted either by stacking on the cold heel of a pot and heating under a controlled environment or pre-heating in a basket over a melt, and then subsequently immersing the load. Melting can also be accomplished by controlled melting, utilizing an induction melting furnace whereas temperature can be slowly increased. Pelletizing pressures range from approximately the yield pressure to the cold welding pressure of the material being reclaimed. A typical pelletizing environment is 20% SF.sub.6 and 80% CO.sub.2 and a suitable melting environment is 98% CO.sub.2 and 2% SF.sub.6.
