“…Reference was made to a table in which extraction data on niobium and tantalum are given for a number of organics (25) in order to select a substitute for the diethyl ketone. After considering extractability, availability, cost, and · the solubility in water~ cyclohexone, diisobutyl ketone, methyl isobutyl ketone (hexane)~ and tributyl phosphate were · selected for test extractions.…”

A procedure for the production of spectrographically pure niobium and tantalum oxides from columbitetantalite concentrates was developed in this study. The procedure involves a caustic fusion process and the separation of tantalum and niobium by liquid-liquid extraction.
