浮选是回收锌湿法冶炼渣中银的重要手段之一。然而,冶炼渣中的可溶性离子对银的浮选行为产生影响,同时冶炼渣粒度、矿物组成等参数亦对浮选效果产生影响。通过工艺矿物学分析与锌冶炼工艺参数分析,优化并设计了最佳浮选回收银流程,并提出了改进浮选法回收锌湿法工艺的银精矿冶|炼方法。研究结果表明,常温常压水浸一浮选法所得的银精矿产率及银回收率均高于直接浮选。最终所得粗精矿银品位3 262.46 g/t、回收率81.84%,实现了银精矿的充分回收。研究方法为银精矿的高效回收提供了参考,有助于解决银资源短缺的问题,并为银的可持续利用提供了新的途径。
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.
