Contents 1 The Possibility of using Solvent - Solvent Extraction
This report investigates the use of solvent-solvent extraction for the secondary concentration of lead and thorium. The extraction reagents investigated in this report are: For the lead extraction: diethlyammonium diethyldithiocarbamate (DDDC) For the thorium extraction: trioctylphosphinc oxide (TOPO) and di-(2-ethylhexyl)phosphoric add (HDEHP). For all of the extractions 2-octanone was used as...
متن کاملSolvent extraction of uranium from leach solutions obtained in processing of Polish low-grade ores
Solvent extraction of uranium from acidic and alkaline post-leaching liquors that were obtained by leaching of Polish ores is reported in this paper. The stripping of uranium from organic to aqueous phase was also studied. The synergistic mixture of 2-diethylhexylphosphoric acid (D2EHPA) and tri-n-butylphosphate (0.2 M:0.2 M) was found as a good extracting agent for uranium. Recovery of uranium...

متن کاملSolvent Extraction Studies on Uranium using Amine Based Extractants and Recovery from Low Grade Ore Leach Liquors
Neste estudo, extratores à base de amina (Alamine 336, Alamine 308, Alamine 304 e Aliquat 336) diluídos em querosene foram usados para extração de urânio e separação de outros elementos associados. Alamine 336 foi o melhor extrator para o processo de extração de urânio de soluções de sulfato quando comparado com outros reagentes à base de amina, Alamine 308, 304 Alamine 336 e Aliquat 336. O com...
