rare earths selenium

Concern grows over China s dominance of rare-earth metals
A second approach to be carried out at Ames will evaluate a wide range of elements including lithium zinc manganese and selenium for combination with rare earths and a transition metal. If successful the newly discovered magnetic materials could require significantly less of the rare earths.

Analysis of rare earth sulfides selenides and tellurides
The rare earth content of sulfides selenides and tellurides is determined by titration with EDTA using Xylenol Orange as indicator. Sulfur is measured by titration of sulfate with lead nitrate solution after removal of rare earths on a cation exchanger. Selenium metal is

Improved method for preparing rare earth
An improved method for the preparation of high purity rare earth sesquichalcogenides is described. The rare earth as one or more pieces of the metal is sealed under a vacuum with a stoichiometric amount of sulfur or selenium and a small amount of iodine into a quartz reaction vessel. The sealed vessel is then heated to above the vaporization

Selenium minerals such as Clausthalite and Naumannite are rare. Selenium usually in the form of metal selenides is the companion of sulphurous ores of the metals copper lead zinc gold and iron. When these ores are roasted the solid selenium dioxide in the fly ash or in the downstream sulfuric acid production collects as selenious acid.
