  • REE

    A rare-earth element (REE) or rare-earth metal (REM), as defined by the International Union of Pure and Applied Chemistry, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Scandium and yttrium are considered rare-earth elements because they tend to occur

  • Rare earth elements mining investment: It is not all

    Despite the complexity of rare earth mineral deposits and the fact that their mining operation usually includes very different by-products (such as zirconium, uranium, manganese, niobium, etc.), the evaluation of rare earth elements mining investments does not present much more difficulty than in the case of single element mining projects.
