The Electrolytic Recovery Of Copper And Zinc From Scrap Brass With Special Reference To Lead-Bearing Brass., Frederick A. Hames

Bachelors Theses and Reports, 1928 - 1970

Several methods have been investigated, with some success, for treating scrap brass to recover copper and zinc, either as pure metals or as salts of the metals. One of the more promising of these methods is electrolysis in sulfate solution for the recovery of pure copper and zinc.
