Patent ID: 10886551

Abstract:
The present disclosure discloses a method for synchronously recovering metal and elemental sulfur, particularly to a method for synchronously recovering metal and elemental sulfur in sulfide ore tailings, and belongs to the technical field of waste recycling. According to the present disclosure, metal and sulfur element are transferred from a solid phase to a liquid phase in the form of ions respectively by leaching the sulfide ore tailings in an anode chamber, then metal ions are recovered in the form of hydroxide precipitate in a first cathode chamber, and sulfate ions are recovered in the form of elemental sulfur precipitate in a second cathode chamber. The method of the present disclosure can synchronously realize the recovery of metal and elemental sulfur in sulfide ore tailings, such that a metal recovery rate is up to 89.4%, and an elemental sulfur recovery rate is up to 45.7%, meanwhile, a process flow is simple, operating cost is low, recovery rates of metal and sulfur element in tailings are high, corrosion of equipment is alleviated, and secondary pollution is avoid.
