For many years, our understanding of the behavior of the REE in hydrothermal systems was
based on semi-empirical estimates involving extrapolation of thermodynamic data obtained …

The hydration and complexation of metals in hydrothermal fluids are key processes
controlling the mobility of elements in the Earth's crust, leading to the formation of ore …

New technologies, particularly those designed to address environmental concerns, have
created a great demand for the rare earth elements (REE), and focused considerable …

Economically exploitable deposits of metallic minerals (ore deposits) form in the Earth's crust
through a variety of geologic processes. These involve extraction of metals at low …

The solubility of REE (III) fluoride solids was determined in fluoride-and chloride-bearing
solutions at 150, 200 and 250° C and saturated water vapor pressure. These experimental …

Rare elements include rare-earth elements (REE), Nb, Ta, Zr, and Hf. As a group, these
elements are concentrated in the crust and are incompatible (remain in the melt rather than …

Abstract The Thor Lake rare metal (Zr, Nb, REE, Ta, Be, Ga) deposits in Canada's Northwest
Territories represent one of the largest resources of zirconium, niobium, and the heavy rare …

Rare earth elements and yttrium (REY) are strategically important materials in the defense,
aerospace, automation and electronic industries, and therefore, REY has been referred as …

The solubility of Nb 2 O 5 and the speciation of niobium in HF-bearing aqueous solutions
have been determined at temperatures of 150, 200, and 250° C and saturated water …

Recent increase of the demand for rare earth elements (REEs), especially dysprosium and
terbium used in the permanent magnet industry is modifying a concept of the REE …
