摘　　要：对含铅重晶石矿进行了化学组成和工艺矿物学研究。对铅与重晶石矿物分别进行了浮选探索与条件试验研究,确定了铅硫混浮-铅硫分离-重晶石浮选的工艺流程。通过确定的选别工艺流程对原矿进行浮选,可获得Pb品位61.43%、回收率81.15%的铅精矿和BaSO_4品位95.95%、回收率97.82%的重晶石精矿,以及产率1.66%、有效硫25.24%的硫精矿副产品。In this paper,the chemical composition and process mineralogy of a lead-barite ore was studied detailedly.The flotation exploration and condition test research were carried on and the lead sulfide mixed floating-separation-barite flotation process of was determined.In the closed-circuit test,the lead concentrate could be got with the Pb grade of 61.43% and recovery rate of 61.43%,while barite ore concentrate could be got including 95.95% of BaSO4 and a recovery rate of 97.82%.Pyrite concentrate whose yield was 1.66% and the grade of effective sulfur was 25.24% was produced.
