Development of Organic Collectors for the Flotation of Uranium Minerals

Description: A series of organic reagents for the collection and flotation of several secondary uranium minerals has been developed, this being the mono-alkyl nitrogen substitutions of the dithiocarbamate grouping with a chain length of at least eight carbon atoms. In flotation tests, using the potassium salt of n-decyl dithiocarbamate as collector, high recoveries of autunite have been obtained from mixtures of finely-ground synthetic autunite and silica sand. Certain base-metal salts added as conditioning… more

Separations of yttrium and some rare earths by liquid-liquid extraction

Description: The use of liquid-liquid extraction for the separation of some inorganic compounds was demonstrated. The yttrium-- rare earth concentrates were obtained from Fergusonite ore, Gadolinite ore, and a by-product from an ion-exchange resin separation process. In each case the mixture in terms of oxide was composed of from 50 to 60% yttrium and 5 to 15% heavy rare earths with the light rare earth fraction constituting the remaining material. Tributyl phosphate was generally employed for exracting nit… more
