Dissolution behavior of the associated rareearth elements

Rare earth elements-bearing minerals, once separated, contain as many as 14 individual rare earth elements (lanthanides and yttrium) that must be further separated and refined. The complexity of extracting and refining rare earth elements is illustrated by a metallurgical flow sheet for the Mountain Pass mine in California (fig. 2). Potential environmental concerns associated with mineral processing Neither thorium-rare earth mineral vein nor carbonatite deposits are likely to have significant associated natural or mine-related acid drainage. Unless all thorium is recovered during mining and milling, waste dumps and tailings contain radioactive materials.
