“Customers that commit to maximum quality when sorting secondary scrap can get a real head start in commercialising their products,” predicts Karl Hoffmann, Sales Director for Metal Recycling at Steinert. X-ray transmission and X-ray fluorescence are the two technologies used to produce pure fractions from aluminium, copper, zinc and brass.
For example, advanced X-ray transmission sorting can be used to remove free magnesium from aluminium scrap, thereby producing high-purity qualities ready for the furnace. The application has been up and running in customer plants for a year now and is producing a verifiable magnesium enrichment rate of up to 94 %. This is an effective and flexible alternative to sorting by density in a sink/float procedure.
The technical application can be retrofitted on most STEINERT XSS-T X-ray transmission sorting systems built from 2016 and later and is already being used by many customers.
