摘要: 针对金红石与石榴石浮选分离过程中羟肟酸类捕收剂选择性好,但捕收能力较弱的问题,以乳化煤油为增效剂,金红石与石榴石单矿物和人工混合矿为浮选对象,对改善水杨羟肟酸(SHA)的捕收能力进行了试验。单矿物浮选试验表明:经Tween80乳化的煤油改善SHA浮选性能的效果最好;相比乳化煤油与SHA混合一步添加,分步添加的浮选效果更佳;增大乳化剂用量能提升金红石的上浮率,乳化剂Tween80与煤油较好的质量比为3.0%。提高矿浆中乳化煤油的浓度,能大幅度提高金红石上浮率,但会影响SHA对金红石和石榴石浮选的选择性。人工混合矿浮选试验表明:以铅离子为活化剂、乳化煤油为捕收增效剂、MIBC为起泡剂,浮选矿浆pH=6.3附近时,较低用量的SHA就能实现金红石与石榴石的高效分离。

Abstract: Salicylhydroxamic acid is a selectivity collector in flotation separation of rutile with garnet,but its collecting power is poor.In this paper,emulsified kerosene was using as collector intensifier to improve the collecting power of Salicylhydroxamic acid (SHA),in order to reduce the dosage of collector.Batch flotation tests of single mineral and artificial mixed mineral were conducted,the results indicated that the emulsifier types,the addition method of emulsified kerosene,mass ratio of emulsifier and kerosene,the concentration of emulsified kerosene can significantly affect the performance on flotation of rutile from garnet.Appropriate dosage of emulsified kerosene can significantly reduce the consumption of SHA,thereby reduce reagent cost.
