Book Description
During recent years increased interest has been shown in the metal niobium. The Atomic Energy Commission has encouraged research on new methods of winning the metal from its ores with the ultimate hope of finding a process which would yield niobium metal at a reasonable price. This report was written to consolidate the more important information available in the literature on the separation of niobium and tantalum.
The Extraction and Separation of Niobium and Tantalum by Liquid-liquid Extraction Using Tri-n-butyl Phosphate

Book Description
The system proposed for the production of niobium and tantalum is liquid-liquid extraction by TBP. The combined niobium and tantalum are extracted with TBP, and the niobium is scrubbed from the organic phase with 4 N sulphuric acid. Any tantalum removed with the niobium is re-extracted with TBP and returned to the extraction circuit. Tantalum is then removed from the organic phase with 8 per cent ammonium fluoride. Recovery figures are given for the various stages of the operation, and equilibrium and settling curves are included. The long-term stability of the process and its final optimization were not investigated, and it is recommended that the optimization should be done during the commissioning of the plant.
