摘　　要：针对某锌选矿厂氧化锌浮选药剂成本高的问题,在试验的基础上,生产中改用摇床重选方法得到的氧化锌精矿品位达35%,锌(硫化锌和氧化锌)总回收率为83%～84%,与改造前浮选指标接近,每年为企业节约药剂成本500多万元。To solve high cost of reagent in zinc oxide ore flotation, the way of tabling was used in actual production based on the experiments. Zinc oxide concentrate of zinc 35% with total zinc （including zinc sulphide and zinc oxide） recovery of 83% -84% was obtained. The technological index was almost the same as that of flotation used in the past and production cost of 5 million yuan was saved annually.
