摘　　要：为了探讨简化铅锌硫化矿石浮选药剂制度的可能性,在选铅时以25#黑药为捕收剂而不使用锌抑制剂的情况下,对蒙古乌兰某铅锌硫化矿石进行了铅锌依次优先浮选试验,结果获得了品位为71.15%、回收率为96.87%的铅精矿和品位为46.41%、回收率为87.89%的锌精矿,银在铅精矿中的品位和回收率可达1 400 g/t和83.90%,铅精矿和锌精矿中的砷含量均在其相应等级品的要求范围内。该结果与浮铅时以25#黑药为捕收剂且使用锌抑制剂相比,铅精矿锌含量高1.07个百分点但铅品位高8.06个百分点,其余指标相当,而且药剂制度和工艺流程大大简化,药剂用量显著减少。In order to discuss the probability of simplifying the flotation reagent system of lead-zinc sulfide ore,preferential flotation tests were carried out on the Wulan lead-zinc sulfide ore in Inner Mongolia with the depressant of 25# aerofloat and without the usage of sphalerite.Lead concentrate with grade of 71.59% and recovery of 96.87% and zinc concentrate with grade of 46.41% and recovery of 87.89% were obtained separately.Furthermore,the grade and recovery of silver in the lead concentrate can reach 1 400 g/t and 83.90%,and the contents of arsenic in the two concentrates can meet the quality requirements.Comparing with the results of using of 25# aerofloat as collectors and sphalerite as depressant,the zinc content of lead concentrate is 1.02% higher,while the lead grade is 8.06% higher,and other indexes are corresponding relatively.By this method,the reagent system and the process can be greatly simplified,and the reagent consumption can be saved dramatically.
