A novel technique has been developed to separate eutectic forming elements using a continuous supply of high pressure molten aluminum. In this continuous process, enriched liquid in the mushy zone is selectively expelled from the solidifying mold through a permeable membrane. The fraction of expelled liquid and the level of purification attained can be controlled in real time. Applications of this technique for refining smelter grade aluminum as well as recycling aluminum scrap are being explored. Unique aspects and advantages of the process will be discussed.
