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.
