9 REE METALS IN EUROPE Finland has been active in mineral strategy work in EU because of increased level of mining industry. Rare Earth Elements and Yttrium are Critical Raw Materials (CRM) which are essential for modern technologies. REE-metals and Yttrium are critical resources in EU and development of the production is needed through active cooperation between EU countries. In 2011, global demand was 105 kt of REY oxides and is expected to grow to 160 kt in 2016 (Hatch, 2012). 9/18
