摘　　要：采用新型捕收剂SF对攀西某辉长岩型钛铁矿进行浮选试验,探索了捕收剂用量、pH调整剂用量、抑制剂种类选择及用量对钛铁矿浮选分离效果的影响,进行了钛铁矿浮选开路、闭路试验。结果表明,采用新型捕收剂SF,通过"一粗两扫四精"浮选流程可有效分离原矿中的钛铁矿和脉石矿物,获得TiO_2品位为48.06%、回收率为86.36%的钛精矿。捕收剂SF用量少、成本低,可实现辉长岩型钛铁矿的有效选别。The flotation of a gabbro ilmenite from Panxi area using a novel collector SF was investigated.The effects of collector dosage,p H regulator dosage,depressants types and dosage on separation of ilmenite and gangue minerals were studied.Furthermore,the open and closed circuit experiments for ilmenite flotation were carried out.The results show that the ilmenite can be effectively separated from gangue minerals in the ore obtaining the ilmenite concentrate with grade of 48.06% and recovery rate of 86.36% for TiO_2,through the processes of ＂one roughing,two scavenging and four cleanings＂using SF as the collector.The consumption of the novel collector and cost are lower,which can achieve efficient sorting for gabbro ilmenite.
