摘　　要：针对低品位硫铁矿精矿品位低不利于焙烧制酸的问题,同时为了有效利用该类低品位硫铁矿资源,对云南某低品位碳质硫铁矿进行了提硫试验研究。试验结果表明,采用新工艺和新药剂402为提硫捕收剂,可以有效降低硫精矿中碳的含量,提高硫品位。试验采用反浮选—正浮选的半闭路试验流程,得到了硫品位为42.25%、回收率为92.96%、含碳量为1.58%的硫铁矿精矿。The sulfide concentrate with a low- grade pyrites was not available for sulfuric acid making via roasting. In order to utilize the low - grade pyrites resources, experiments were carried out aiming at a low -grade pyrites which contain carbon elements in Yunnan province. The results showed that using new reagent 402 as collector and by reverse flotation process could efficiently re- duce the content of carbon and enhance the grade of S in the concentrate. Finally, the concentrate of S 42.25% with a recovery of 92.26% which contains 1.58% carbon was obtained by half closed circuit reverse flotation -direct flotation flowsheet.
