摘　　要：这是一篇矿物加工工程领域的论文。攀西地区是我国最大的钒钛磁铁矿资源基地,伴随着钒钛磁铁矿的开采和选冶,产生了巨量的尾矿。攀西钒钛磁铁矿尾矿中钒、钛、铁、铜、钴、镍、磷、钪等战略性元素的含量较高,具有潜在的回收价值,但尚未开展系统的选矿回收实验。通过对攀西地区红格矿区尾矿工艺矿物学的研究,拟定了尾矿中战略性元素综合利用技术路线,并开展了系统的选矿回收实验。以浮选选硫—弱磁选铁—强磁浮选选钛—强磁尾矿浮选磷为技术路线,获得了钴品位为0.175%的硫钴精矿、TFe品位56.57%的铁精矿、TiO_(2)品位45.97%的钛精矿、P_(2)O_(5)品位31.73%的磷精矿。研究表明,通过系统的选矿回收实验,能够减少尾矿排放量21.3%,并且,回收这些战略性矿产能获得年产值7134.89万元。因此,回收攀西地区钒钛磁铁矿尾矿的战略性矿产,具有良好的经济效益和社会效益。This is an essay in the field of mineral processing engineering.Extraction of the vanadium titanomagnetite ore deposits in the Panxi Region,the biggest vanadium titano-magnetite mineral resource base,results in the production of a significant volume of tailings.The tailings have a high recovery potential of the strategic mineral resources(eg.,Vi,Ti,Fe,Co,Cu,Ni,P,and Sc).Based on the process mineralogy study,we determine the comprehensive utilization technology flowsheet and conduct a systematic recovery test of tailing samples from the Hongge mine in the Panxi Region.By the process of(1) flotation of sulfur,(2) lowintensity magnetic separation of iron,(3) high-intensity magnetic separation and flotation of titanium,(4) flotation of Phosphorous,we obtain the sulfur-cobalt concentrate(Co 0.175%),the iron concentrate(TFe56.57%),the titanium concentrate(TiO_(2) 45.97%) and phosphorous concentrate(P_(2)O_(5) 31.73%).These results show that the systematic recovery test of tailings can reduce the production of a volume of tailings with significant economic and social benefits.
