Fe in Al-Si cast alloy scrap melt was eliminated by electromagnetic filtration of primary iron-rich phases, which were formed by adding Mn in the melt. The principle of electromagnetic filtration is that the electromagnetic force scarcely acts on the primary iron-rich phases due to its low electric conductivity as compared to the melt. As a result, …
