This paper investigates the comprehensive processing of technogenic clinker waste generated during zinc production for the recovery of valuable metals. A technological approach consisting of microwave roasting, wet magnetic separation, and hydrometallurgical leaching was applied. The effects of microwave roasting temperature, power, and duration on carbon removal and changes in the metallic phases of the clinker were investigated. The optimum roasting duration was determined to be 60 minutes. During the subsequent magnetic separation stage, the major part of iron was transferred to the magnetic fraction, while non-ferrous and precious metals were concentrated in the non-magnetic fraction. Silver was leached using Jinchan reagent in the presence of hydrogen peroxide. The obtained results demonstrate the practical potential of the proposed approach for the comprehensive treatment of technogenic waste and efficient recovery of valuable metal components.Keywords
