Sodium tungstate solution precipitation purification method
Introduction
Tungsten is a metal that is widely used for many industrial purposes and tungsten acid sodium (Na2WO4) is one of the most important compounds derived from it. This compound is mostly used in electroplating, as a catalyst in synthetic processes, as a corrosion inhibitor, in paints and......
Germanium Extraction by Classical Chlorination
Chlorination Method for Extracting Tungsten
Tungsten is a metal commonly used for the production of alloys, magnets, and cutting tools, as well as for its radiation shielding properties. However, in order to be able to use tungsten, it first needs to be extracted from its ores. One of the most co......
Chromatographic separation of rare earth elements
Rare-earth elements (REEs) are a group of 17 chemical elements in the periodic table, namely scandium (Sc), Yttrium (Y), and 15 lanthanides. The term “rare earths” name was first used in 1827 by Swedish chemist, Carl Axel Arrhenius, but the elements themselves were not discovered until late 18-1......
