This degree of separation of fines simply could not be achieved using dense media plant technology/ sink-float separation process. And, until now, it wouldn’t even have been possible using TOMRA’s sensor-based sorting technology because magnesium is very similar in density to aluminum so the technology couldn’t recognize the difference between the materials. Now, the capabilities and combination of the x-ray technology used in our X-TRACT makes it by far the most consistently accurate solution to date.
Brian Gist, Global Sales Director Metals at TOMRA Sorting Recycling, comments: “We are thrilled to be the first company in the world to create furnace-ready products, including Low Magnesium Twitch, across the full size fraction spectrum to remove the need to process Zorba by Dense Media Separation. There is, without doubt, a strong internal domestic market in the United States for low-magnesium twitch production but metal processors simply haven’t been able to access it until now because of the high purity requirements of the US secondary aluminum smelters.
