Outline of Final Research Achievements	About twenty kilo ton of magnesium per year is used for aluminum alloy such as Al-Mg-Si alloy.During dross formation, not only magnesium but also molten aluminum is oxidized. It is very important to control the Mg concentration for sustainable Al recycling.In this work, Mg removal from molten Al by vacuum processing with ceramic filter. Mg was removed from Al-10%Mg alloy at 800 degreeC and 1Pa vacuum condition.
