| 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.

| Abstract: | 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 reduce 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. |
