摘　　要：在浮选动力学的基础上研究了金红石浮选工艺,充分利用金红石和脉石矿物的浮选速度差异,实现浮选分离。通过控制粗选、扫选时间,中矿单独再处理等方法,开路试验最终获得精矿Ti O2品位和回收率分别为70.00%和55.67%的良好浮选指标。The flotation technique for rutile was studied based on the flotation kinetics. Flotation separation of rutile and gangue can be achieved by using the difference in their flotation speed. By controlling the flotation time of roughing and scavenging,and merged handling of middlings,an open-circuit test yielded good flotation indices,indicating the final concentrate with Ti O2 grade and recovery of 70.00% and 55.67%,respectively.
