  • RECOVERY OF RARE EARTHS FROM INDUSTRIAL WASTE

     · Very efficient pyrometallurgical processes have been developed for the recovery of metal values from electronic scrap spent automobile exhaust catalysts and spent industrial catalysts. In its Hoboken site near Antwerp (Belgium) Umicore operates an integrated smelter and refining plant for recovering metals from Waste Electrical and Electronic Waste (WEEE). The list of recovered metals includes silver gold platinum-group metals (platinum palladium ruthenium rhodium iridium) indium bismuth tin selenium tellurium antimony arsenic and the base metals copper nickel and lead. However the employed metallurgical flow sheets have not yet been developed for recovery of rare earths. Because of the high affinity of the REEs for oxygen the REEs end up in diluted (oxidic) form in the slag of the so-called "copper smelter" and finally in the slag
