<p>Disclosed is a hydrometallurgical method of metal sulfides, comprising: 1) adding a metal A sulfide into a leaching solution and finally generating a metal A complex, elemental sulfur and a reduced catalyst; and 2) filtering the leaching solution treated in step 1) and containing the metal A complex, the elemental sulfur and the reduced catalyst, injecting the leaching solution into an electrolytic bath, using an inert electrode as an anode and using metal A or an inert electrode as a cathode, and performing electrolyzing to obtain the metal A at the cathode. Compared with a conventional strong acid leaching process, the method in the present invention greatly reduces the corrosion on a device. According to the present invention, continuous circulation of leaching sulfides by using the leaching solution and regenerating the leaching solution is implemented by using a proper catalyst, a complexing agent and an electrolytic method.</p> |
