摘　　要：安徽某硫铁矿矿石属低铜高硫矿石,含铜0.3%、硫34.95%、铁42.64%,目前采用优先浮铜工艺,产出铜精矿和硫精矿,铁未回收。针对该矿物采用先浮后磁常规方法得到铁精矿,再以2#油作起泡剂,硫酸和硫酸铜作调整剂和活化剂,煤油和丁黄药作捕收剂进行了铁精矿脱硫全流程闭路试验,可得到含铜10.98%、铜回收率77.78%的铜精矿及含铁65.38%、含硫0.84%、铁回收率11.78%的铁精矿,效果较理想,能有效提高资源综合利用率。A low copper-high sulfur pyrite ore with copper,sulfur and iron content of 0.3%,34.95% and 42.64%,respectively,was currently beneficiated adopting a technique of copper preferential flotation,and a copper concentrate and a sulfur concentrate were obtained therein,yet,iron minerals were discharged in the tailings.To recover iron minerals,a classical process of flotation-magnetic separation was adopted to obtain iron rough concentrate,and then,a desulphurization closed-circuit test on iron rough concentrate was conducted using 2# oil as the frother,sulfuric acid as the regulator,copper sulfate as the activator,and,kerosene and butyl xanthate as the collectors,therewith,a copper concentrate with a copper grade and recovery of 10.98% and 77.78%,respectively,and an iron concentrate with an iron content of 65.38%,a sulfur content of 0.84% and an iron recovery of 11.78%,can be recovered.
