A process for separating thorium compounds from

 · the remainder of the rare earths by neutralization of the filtrate from the rare earth separation to a pH of with ammonium hydroxide. The precipitates from each fraction were thickened and filtered. The overall recovery of thorium was 9697 per cent of rare earths 9899 per cent and of uranium 535 per cent.

RARE EARTHS REPORTResource World Magazine

Rare Earth Salts of Beatrice Nebraska has developed an environmentally friendly technology for the separation and purification of REEs that provides a significant operational and capital cost advantage over solvent extraction methods. Its technology is proven at commercial scale and functions on a broad range of rare earth concentrates.

Improved methods for magnetic purification of malaria

201196 · cytes 7 . Although magnetic purification is increasingly employed in the field of malaria research the relationship between magnetic field strength and haemozoin yield during magnetic purification procedures has not previously been examined. Therefore the performance of three configurations of permanent rareearth neodymium magnets producing

An overview on membrane strategies for rare earths

 · As for REEs separation Tian et al. had summarized the nonprecipitation methods to treat REEs from the leach liquor of rare earth ores and Wang et al. had overviewed the separation and purification of Sc by multiple technologies including solvent extraction and related techniques. To our knowledge few summaries on the separation of REEs by

Industrial countercurrent chromatography separations

In hydrometallurgy traditional extraction technologies in particular for isolation and purification of rareearth metals include a number of processing steps using up to hundreds of mixersettler extractors. These technologies could be greatly simplified by using the methods of countercurrent chr

HOME Calciumsolutions

The Calciumbased Mineral Purification (CMP) process reacts with impure calciumbased minerals with a reagent solution at a moderate temperature and pressure. Contaminants can then be released and separated out of the reagent solution. The product is then converted to purer brighter chalk or gypsum and separated out of the reagent solution.
