THE ROLE OF SCANDIUM CHLORIDE AND HYDROXIDE COMPLEXES IN THE FORMATION OF SCANDIUM DEPOSITS: INSIGHTS FROM EXPERIMENTS AND MODELING

Economic Geology, 2023
Abstract Although scandium is commonly concentrated to economic levels by magmatic processes, hydrothermal fluids also play an important role in its concentration. Indeed, the most important source of scandium is currently the Bayan Obo deposit in China, where scandium is extracted from hydrothermally produced aegirine.

Sc2[Se2O5]3: The First Rare-Earth Metal Oxoselenate(IV) with Exclusively [Se2O5]2− Anions

Crystals, 2018
The scandium oxodiselenate(IV) Sc2[Se2O5]3 was synthesized via solid-state reactions between scandium sesquioxide (Sc2O3) and selenium dioxide (SeO2) with thallium(I) chloride (TlCl) as fluxing agent in molar ratios of 1:4:2.

Sorption of Scandium from Acidic Chloride Solutions on Strong-Acid Cation-Exchange Resins: Comparative Assessment and Isotherm Modeling

Metals
Recovery of scandium from chloride-bearing process liquors formed during titanium–magnesium production remains constrained by trace-level metal content and chemically aggressive solution matrices. Within the present study, the retention behaviour of Sc3+

Transcriptomic Analysis of Pleiotropic Effects of Scandium Chloride on C2C12 Myoblasts

Toxics
The effects of scandium on skeletal muscle cells remain poorly understood. This study aims to determine whether scandium chloride (ScCl3) affects C2C12 myoblast proliferation, and the cellular responses were assessed using CCK-8, flow cytometry, RNA-seq,
