摘要: 针对我国高硫铝土矿难以利用的现状,以广西某高硫铝土矿为研究对象,采用反浮选脱硫—聚团浮选脱硅原则流程和新型高效铝土矿浮选捕收剂ZY-01进行了选矿试验。确定的选矿工艺流程为1粗1扫1精反浮选脱硫—1粗2扫2精聚团浮铝降硅;采用该流程获得的铝土矿精矿Al2O3品位为63.31%、回收率为78.52%、铝硅比为7.38,硫精矿S品位为16.78%、回收率为80.72%。铝土矿精矿指标满足氧化铝生产要求。

Abstract: Aiming at the difficulty in utilizing high sulfur bauxite,beneficiation experiments of desulfurization by reverse flotation and desilication by aggregation flotation and an efficient bauxite collector of ZY-01were carried on the high sulfur bauxite in Guangxi.The aluminum concentrate with alumina-silica ratio 7.38,alumina grade of 63.31%,recovery of 78.52% and the sulfur concentrator with 16.78% sulfur and recovery of 80.72% were obtained through the desilication reverse flotation process of one roughing-one cleaning-one scavenging and aggregation flotation process of one roughing-two cleaning-two scavenging.The aluminum concentrate can meet the production requirements for alumina oxide.
