| 21. | What is " Fractional Solvent Extraction "?
|
| 22. | It is prepared by solvent extraction from the mixed lanthanides isolated from bastn�site ( or monazite ).
|
| 23. | In Turkey, a water extraction process is used, while in Tasmania, a solvent extraction process is used.
|
| 24. | The synthesis of the BTBPs as solvent extraction reagents was a development of the chemistry at axial sites.
|
| 25. | The absolute may be further processed to remove any impurities that are still present from the solvent extraction.
|
| 26. | Special use in nuclear industries for fuel reprocessing, where spent fuel from reactors is subjected to solvent extraction.
|
| 27. | Seedlac which still contains 3 5 % impurities is processed into "'shellac "'by heat treatment or solvent extraction.
|
| 28. | Such carbonate concentrates can be treated by a solvent extraction and electrowinning ( SX-EW ) plant or smelted.
|
| 29. | Solvent extraction and electrowinning ( SX / EW ) operations started in 1988 and have run continuously since.
|
| 30. | The nonvolatile alkaline fission products and minor actinides is most suitable for further processing with'dry'SANEX, which use solvent extraction.
