摘　　要：在不改变浮选生产主流程的前提条件下,针对伴生金银的赋存状态和载体矿物的特性,通过改善药剂制度,使更多的金银矿物富集在铅精矿中,提高铅锌矿伴生金银的回收率。金回收率提高9.51个百分点,银回收率提高2.4个百分点。Under the precondition of not changing the main flow of flotation process, through the analysis of the occurences state of the gold and silver and the characteristics of the carrier minerals and the improvement of the reagent system, more gold and silver minerals are enriched in the galena concentrate. The recovery rate of associated gold and silver has increased in lead zinc mine. Gold recovery rate increased by 9.51 percentage points, and silver recovery rate increased by 2.4 percentage points.
