[Isotope-prod] Gallium extraction before chemical processing

[Pavel Degtiarenko]

Hi All,
Found an interesting paper discussing Ga purification process via 
electrolysis, using the GaCl4 electrolyte. They claim they can do 
gallium purification to extremely high levels in one run, with 
productivity of 1 kg of pure metal per day. That would mean few hours 
for our 100-200 g targets. I guess it can be accelerated if needed, 
either by design, or by parallel runs. The idea would be to run the 
electrolyzer before the chemical separation, return, say, 99% of pure 
gallium ready for the next irradiation right away, and then chemically 
separate Cu-67 from the residuals. That would help increase Cu-67 
concentration and make the amount of material for chemical separation 
small, to avoid known difficulties of working with large volumes.
Best regards,
Pavel
