摘　　要：攀西某低品位钛铁矿含TFe17.14%、含TiO_(2)6.32%,由于原矿铁、钛品位低,目前处于待开发状态,为铁钛并重、高效开发该资源,采用预选工艺,提前抛除部分尾矿,降低入磨量,提高入选品位,达到降低成本的目的,进行了不同粒级的预选试验研究,确定了最佳的预选流程,在-3 mm粒级进行湿式预选,抛尾产率29.51%,预选精矿含TFe 20.74%、TiO_(2)7.97%,铁、钛回收率分别为86.34%、86.58%。A low-grade ilmenite in Panxi region contains TFe 17.14% and TiO_(2)6.32%, which is currently in the undeveloped state. For the equal and efficient exploitation and utilization of Fe and Ti in the ore, research on pre-concentration to remove part of tailings, reduce grinding amount and increase feed grade was conducted. For the sake of reducing cost, pre-concentration experiments with different grain sizes were conducted and the following optimized flowsheet with optimum parameters were obtained. Wet pre-concentration of raw ore with particle size of-3 mm was processed to realize the yield of tailing discharge 29.51%. The concentrate was obtained with Fe grade of 20.74% and TiO_(2)grade of7.97%, Fe and TiO_(2)recovery rate of 86.34% and 86.58% respectively.
