The invention discloses a silver guidance, recovery and beneficiation method in a copper-lead-zinc sulfide ore separation process. The method provided by the invention comprises the steps of selecting raw ore; grinding the ore; bulk-flotating copper, lead and silver; bulk-flotating copper and silver; bulk-flotating lead and silver; bulk-flotating zinc and sulfur; and separating zinc and sulfur, so that an adjusting agent and a collecting agent are further optimized, and finally a copper-silver concentrate, a lead-silver concentrate, a zinc concentrate and a sulfur concentrate are finally obtained. According to the method provided by the invention, not only is a copper-lead-zinc sulfide ore separation effect good, but also the silver recovery rate in the copper-lead concentrate is greatly improved, the comprehensive utilization rate of silver resources applied in mine enterprises is greatly improved, and the economical benefit is remarkable. 本发明公开了种铜铅锌硫化矿分离过程中银导向回收选矿方法。本发明方法包括原矿选取、磨矿、铜铅银混合浮选、铜银混合浮选、铅银混合浮选、锌硫混合
