9. A process of recovering valuable metals from superalloys comprising, decomposing a superalloy electrochemically in an apparatus comprising an anode and a cathode, and with an electrolysis voltage and an electrolysis current, wherein,
(i) the superalloy is used both as the anode and as the cathode, (ii) the polarity of the electrolysis current is reversed with a frequency of from 0.005 to 5 Hz, (iii) said electrolysis voltage is from 2 to 6 volts, and (iv) said electrolysis current is constant.
