摘要 云南建水半风化钛铁矿入选品位Ti O25.42%、TFe 12.02%,主要的钛矿物为钛铁矿,主要的铁矿物为钛磁铁矿。对于高梯度强磁粗选抛尾所获得的钛粗精矿,常采用"摇床"传统工艺精选。而本研究则创新性地提出了"螺旋溜槽—强磁"联合精选新工艺,解决了摇床因占地面积大、台数多,难以建较大规模选矿厂的难题。原矿经"粗磨—强磁抛尾—螺旋溜槽精选—钛粗精矿再磨—强磁再精选"新工艺选别后,获得了钛精矿产率4.56%、Ti O241.63%、钛回收率38.23%;铁精矿TFe 54.74%、铁回收率14.80%的较好指标。 The semi-weathered-type ilmenite ore sample from Yunnan had a head grade of 5. 42% TiO2 and12. 02% TFe,the main titanium-bearing mineral and iron-bearing minerals were ilmenite and titanic magnetite respectively. The rough concentrate of titanium obtained by high gradient magnetic separation was usually processed by gravity concentration with shaking table. This study raised creatively a new concentration technology of "spiral chute- high-intensity magnetic separation",in order to solve the problem associated with building mineral processing plant occupying large area with a large number of shaking tables. The crude ore was processed with the technology of "coarse grinding- high-intensity magnetic separation- concentration by spiral chute- regrinding of rough concentrate of titanium- concentration by high-intensity magnetic separation ",obtaining a titanium concentrate and an iron concentrate. The titanium concentrate had a mass pull of 4. 56%,grading at 41. 63% TiO2 with a titanium recovery of 38. 23%; the iron concentrate assayed 54. 74% TFe with an iron recovery of 14. 80%.
