Flotation is a critical method for recovering silver from zinc hydrometallurgical residue. However, soluble ions in the residue, along with parameters such as particle size and mineral composition, significantly influence silver flotation behavior. Through process mineralogy analysis and evaluation of zinc hydrometallurgical parameters, this study optimized and designed an optimal silver recovery flotation process. An improved flotation method for refining silver concentrate from zinc hydrometallurgical residue was proposed. Results demonstrate that the water leaching-flotation method under ambient temperature and pressure achieves higher silver concentrate yield and recovery rates compared to direct flotation. The final rough concentrate attained a silver grade of 3 262.46 g/t with a recovery rate of 81.84 %, enabling efficient silver recovery. This approach provides a reference for high-yield silver concentrate refining, contributes to addressing silver resource scarcity, and offers a new pathway for sustainable silver utilization.
