Steinert has a product line that uses XRF to sort different alloys in mixed aluminum scrap: https://youtu.be/td8IDt2ke1E?t=96 https://youtu.be/td8IDt2ke1E?t=96

Mixed metal recycling can now achieve very high recovery rates. Air-jet sorters with vision systems have been around for decades, usually for agricultural products. Throughput is huge and cost is low. It's possible to sort individual rice grains.[1] Most vegetables in US supermarkets today have been through an automatic sorter. So now this has made it to metals.
