| 摘 要： | 江西某硫尾矿中有用矿物主要为白钨矿，WO3含量为0.22%。为确定该尾矿中白钨矿的回收工艺，在实验室进行了选矿试验。结果表明：试样采用1粗3精3扫常温浮选，常温精矿以水玻璃为脱药剂在90 ℃下搅拌脱药，再采用1粗4精3扫加温浮选流程处理，最终得到WO3品位为67.03%、回收率为76.17%的白钨精矿。

| Abstract: | The sulfur tailings from Jiangxi contain 0.22% WO3 .For determining the recovery process of scheelite from tailings,the mineral processing experiments were investigated in lab.The results show the scheelite concentrate with WO3 grade of 67.03% and recovery of 76.17% can be got by adopting the normal temperature flotation of single-stage roughing,three-stage cleaning,three-stage scavenging,sodium silicate as reagent removal agent,stirring at 90 ℃,then the heating flotation of cleaning flowsheet of single-stage roughing,four-stage cleaning and three-stage scavenging process. |
