摘要
本文分析了攀枝花选钛厂现行选钛生产工艺，指出了粗选作业（螺旋和溜槽）难以控制和微细粒级物料未入选是造成选钛回收率低的主要原因。根据物料性质及现有选钛工艺，提出了选钛新工艺流程。扩大试验结果表明，对粗、细粒级物料，采用重选－强磁－电选新工艺，对微细粒级物料，采用强磁－浮选新工艺，可使选钛总回收率达到４０％以上，且过程稳定，易于工业实现。
The paper analyses the present production techniques for titanium concentra-tion of the Panzhihua concentration plant,concluding that low titanium recovery resultsmainly from difficulty in cohtrol of roughing operation and no separation of extremely finematerial.According to characteristics of the feed,the author develops a new process flow-sheet for titanium concentration. The results obtained bv its extensive test show that overalltitanium recovery of 40%can be achieved by gravity separation-high intensity magnetic sepa-ration-electrostatic separation of coarse feed and high intensity magnetic separation-flotationseparation of extremely fine feed.The process technology is characterized by steady opera-tion and easy of industrialization.
