If rare-earth metals can be extracted from previously quarried ore, the environmental hazards of new mines and mining waste can be mitigated. In his doctoral research, Wenzhong Zhang from the Department of Chemistry at the University of Helsinki developed a new material by which scandium, a rare-earth metal, can be extracted from the waste of the aluminium industry.
