Journal ArticleDOI
Hydrophobicity of rare-earth oxide ceramics
TL;DR: This work shows that a class of ceramics comprising the entire lanthanide oxide series, ranging from ceria to lutecia, is intrinsically hydrophobic, and attributes their hydrophobicity to their unique electronic structure, which inhibits hydrogen bonding with interfacial water molecules.
Journal ArticleDOI
Modelling of calcium sulphate solubility in concentrated multi-component sulphate solutions
TL;DR: In this article, the chemistry of several calcium sulphate systems was successfully modelled in multi-component acid-containing sulphate solutions using the mixed solvent electrolyte (MSE) model for calculating the mean activity coefficients of the electrolyte species.
Journal ArticleDOI
Process investigation of the acid leaching of rare earth elements from phosphogypsum using HCl, HNO3, and H2SO4
TL;DR: In this article, the feasibility of acid leaching of rare earth elements (REEs) from phosphogypsum from both theoretical and practical standpoints was investigated from both practical and theoretical point of view.
Journal ArticleDOI
Role of surface oxygen-to-metal ratio on the wettability of rare-earth oxides
TL;DR: In this paper, the authors demonstrate how surface stoichiometry and surface relaxations can impact wetting properties of rare-earth oxides (REOs) and show that freshly sputtered ceria is hydrophilic due to excess surface oxygen (shown to have an O/Ce ratio of ∼3 and a water contact angle of ∼15°).
Journal ArticleDOI
Technospheric Mining of Rare Earth Elements from Bauxite Residue (Red Mud): Process Optimization, Kinetic Investigation, and Microwave Pretreatment.
TL;DR: This novel process of “H2SO4 leaching-coupled with-microwave pretreatment” proves to be a promising technique that can help realize the technological potential of REE recovery from secondary resources, particularly bauxite residue.
