摘　　要：钛是一种战略稀有金属,我国钛资源储量丰富,但综合利用率还有待进一步提高。目前钛铁矿矿物加工(选矿)主要采用“磁选+浮选”的联合工艺流程,强化钛铁矿和脉石矿物的选择性浮选分离是提高钛铁矿回收率的关键,本文对现有报道的钛铁矿表面改性(表面溶解、微波处理、离子活化以及其他表面改性手段如氧化焙烧、超声波预处理等)研究现状进行了论述,并对表面改性强化钛铁矿浮选回收的原理进行了分析与探讨,为后续有针对性的指导钛铁矿浮选研究指明了方向。Titanium is a strategic rare metal.China has rich reserves of titanium resources,but the comprehensive utilization rate needs to be further improved.At present,ilmenite mineral processing(ore dressing)mainly adopts the combined process of"magnetic separation+flotation".Strengthening the selective flotation separation of ilmenite and gangue minerals is the key to improving the recovery rate of ilmenite.The reported research status of ilmenite surface modification surface dissolution,microwave treatment,ion activation,and other surface modification methods such as oxidation roasting,ultrasonic pretreatment,etc.is discussed.And the principle of surface modification to strengthen ilmenite flotation recovery is analyzed and explored,which points out the direction for the follow-up targeted guidance of ilmenite flotation research.
