摘要
这是一篇矿物加工工程领域的论文。本研究针对攀西某选厂超微细粒物料进行了超微细粒钛铁矿选矿回收实验研究,确定了强磁预富集-浮选的整体工艺流程,获得了优化的选矿回收工艺流程及条件参数,应用了适用于该类超微细粒钛铁矿回收的浮选药剂EM-A和EM326。结果表明,通过强磁预富集-浮选脱硫+浮选脱泥+一粗一扫五次精选中矿再选返回的选钛流程,最终可获得钛精矿产品TiO_(2)品位45.56%,回收率47.10%的良好指标,为该类超微细粒物料中钛铁矿资源回收提供了技术参考。
This is an essay in the field of mineral processing engineering.This study conducted a test study on the recovery of Ilmenite from an Ultrafine Fine Particle Material in Panxi,determined the overall process flow of strong magnetic preconcentration flotation,obtained the optimized beneficiation and recovery process flow and condition parameters,and applied the flotation reagents EM-A and EM326 suitable for the recovery of this type of ultrafine ilmenite.Results show that through the titanium separation process of strong magnetic preconcentration flotation desulfurization + flotation desliming + one roughing and one sweeping five times of cleaning middlings in the beneficiation and return,the titanium concentrate product TiO_(2) grade of 45.56% and the recovery rate of 47.10% can finally be obtained,which provides a technical reference for the recycling of titanium ilmenite in this kind of ultrafine materials.
