PROCESS FOR ELECTROCHEMICAL DECOMPOSITION OF SUPERALLOYS

A process for recovery of valuable metals from superalloys by electrochemical decomposition is described, both electrodes being formed by the superalloy and the polarity of the electrolysis current being reversed with a frequency of from 0.005 to 5 Hz.
