US5176878A Zirconiumhafnium Separation Process Google

A process for separating zirconium values from hafnium values wherein an aqueous solution of ZrCl 4 and HfCl 4 is contacted with NH 4 SCN, feeding the resultant solution into a solvent extraction system containing aqueous HCl and MIBK, separating off the solvent phase containing MIBK, HSCN, hafnium thiocyanate complex, and any decomposition products of HSCN to leave the aqueous phase raffinate.Separation of hafnium from zirconium using tributyl phosphate Abstract The separation of hafnium from zirconium using tributyl phosphate offers interesting alternatives to present methods for making reactorgrade zirconium. Feed solution for the extraction step can be prepared from the reaction product of caustic and zircon sand.

Fabrication Of Zirconium Alloy Cladding Tubes And Other

1. in the process for separating hafnium from zirconium values which comprises contacting a feed material containing zirconium and hafnium tetrahalides, said tetrahalides being selected from the group consisting of tetrachlorides, tetrabromides and tetraiodides, with water to form an aqueous feed solution, contacting said aqueous solution in a separation step with ammonium thiocyanate, methyl.The calutrons were no longer needed to separate uranium, this unusual and highly difficult separation of hafnium from zirconium was readily undertaken by Y12. However, this was a chemical separation process rather than an electromagnetic separation. Finis “Pat” Patton told me the details of this process. When he came to Y12 recently for a.

extraction of zirconium from the ore

Zirconium and hafnium separation with molten salt extraction in Sn . May 26, 2016 Zirconium and hafnium separation with molten salt extraction in .. process for nucleargrade zirconium production from crude zirconium ore.A process for selective separation of strontium82 and strontium85 from proton irradiated molybdenum targets is provided and includes dissolving the molybdenum target in a hydrogen peroxide solution to form a first ioncontaining solution, passing the first ioncontaining solution through a first.Usually, liquid extraction method is applied for the separation of zirconium and hafnium and several systems have been developed. Distillation of molten salt is also developed for the separation process. However, all of the process above is expensive compared with common metal purification processes.

Zirconium Wikipedia

Separation of zirconium and hafnium by solvent extraction using mixture of TBP and Cyanex 923. The results of this study shows that proposed mixture of TBP and Cyanex 923 can be used successfully in the Zr/Hf separation process without risk of third phase formation.
