Refining Zinc By Electrolysis
Recent advances in the recovery of germanium during the zinc refining …
Subsequent electrolysis of 1–5% germanium-citrate solution by adding 5% acetic acid and propylene glycol, followed by electrodeposition on copper foil, could obtain nanostructured germanium anode [69]. The presence of humic acid can significantly affect the form of germanium present in water. ... In zinc refining processes, many phases ...
