Device for recovering silver by desulfurizing zinc sulfide through leaching residue treatment

The invention discloses a device for treating zinc sulfide leaching residues, desulfurizing and recovering silver, which is characterized by comprising a cavitation cylinder, a support frame, support legs, a driving rod and a controller, the supporting legs are hinged to the supporting frame and turn over towards the lower portion of the supporting frame, the driving rods are hinged to the supporting frame and turn over towards the upper portion of the supporting frame, the ends of the driving rods are hinged to the periphery of the cavitation cylinder, and the controller is fixedly arranged on the upper end face of the support. According to the cavitation treatment device provided by the invention, an ultrasonic, stirring and vibration combined form is adopted to promote slurry to generate a cavitation effect in the cavitation cylinder, so that silver attached to the outer surface of elemental sulfur falls off, and flotation silver removal treatment in the next step is facilitated; wherein cavitation can be
