以富含氧化铁的黄铁矿烧渣为固硫剂 ,进行了脆硫铅锑精矿短回转窑还原造锍熔炼半工业试验 ,取得了铅、锑的直收率分别大于 63 .5 0 %、88.0 2 % ,固硫率大于 95 %的实验结果 ,表明脆硫铅锑矿还原造锍熔炼工艺是可行的。短回转窑具有可用热效率高 ,熔炼强度大的优点 ,可作为脆硫铅锑矿精矿还原造锍熔炼的熔炼设备

The iron oxide-rich pyrite cinder was used as the sulfur-fixing agent, and the semi-industrial test of reducing sulfur matte smelting by short rotary kiln of lead, sulfur and antimony concentrate was carried out. The direct yield of lead and antimony was over 63.50 %, 88.0 2%, and the sulfur fixation rate is more than 95%, which shows that it is feasible to reduce the matte smelting process of the JASM. Short rotary kiln has the advantages of high thermal efficiency, large melting strength, can be used as a smelting equipment for crushing sulfur lead antimony ore concentrate reduction matte smelting
