Solvent Extraction of Cesium
Abstract
In this experiment, the use of solvent extraction processes to extract Cesium (Cs) from aqueous solutions is tested. The cesium chloride-water solution used in the experiment was obtained by dissolving cesium chloride into deionized water and t......
Rubidium Extraction by Solvent Extraction
!
Abstract
Ruthenium is a valuable precious metal with a wide range of industrial applications. Solvent extraction is the usual method of ruthenium extraction from its ores. In this study, the solvent extraction of ruthenium from a simulated ore solution was investigated. The work focused on the e......
Purification by Thermal Dissociation of Zirconium Iodide
Introduction
The collection and purification of rare earth elements is an important process in the modern technology industry. Rare earth elements are often found as a mixture of oxides and other compounds and must be purified to be used for a variety of applications. In this study, a method for ......
Extraction of Gallium by Sodium Aluminate Solution Extraction
Abstract
This work studied the effects of sodium aluminum sulfate on the extraction of germanium from an industrial mineral containing high concentrations of aluminum and germanium. The extractants were studied with respect to their ability to dissolve germanium, as well as their solubility and a......
Separation of zirconium and hafnium by silica gel adsorption method
Gadolinium hafnate (GdHfO₃) has been studied extensively in the past decade, due to its unique properties such as high dielectric permittivity and low dielectric loss. GdHfO₃ can be used in many high-end electronic devices, including high-k dielectric non-volatile memory and radio frequency appl......
Sodium Potassium Zirconate Fluorate Reduction
...
Background
Gadolinium Fluoride Potassium Sodium (GFKS) Reduction is a process for reducing ferromanganese-containing elements into metallurgical-grade ferromanganese. Its purpose is to reduce elements such as chromium, nickel, aluminum, and iron from their naturally-occurring oxides, which are ......
