摘要/Abstract

摘要： 以攀枝花钛选厂的强磁精矿为研究对象，通过浮选试验、浊度试验和扫描电镜分析，系统研究了高强度调浆对钛铁矿浮选的影响及其作用机制.研究发现，经捕收剂诱导疏水后，钛铁矿与钛辉石颗粒间容易发生异相团聚现象，细粒钛辉石随钛铁矿进入精矿产品，造成钛辉石的非选择性上浮.经高强度调浆处理，精矿TiO₂品位大幅提升.浮选指标由常规调浆处理时的精矿TiO₂品位39.97%，回收率78.09%，提升至精矿TiO₂品位43.79%，回收率79.28%.高强度调浆产生的流体力场能够消除钛铁矿与钛辉石颗粒间的异相团聚，强化钛铁矿与钛辉石颗粒间的分散状态，是高强度调浆提升钛精矿TiO₂品位的内在原因.

关键词: 钛铁矿；钛辉石；浮选；异相团聚；高强度调浆

Abstract: The effect of high-intensity conditioning on the flotation of ilmenite was systematically studied via flotation experiment， turbidity experiment and SEM-EDS. Ore samples are derived from the concentrate of high-intensity magnetic separation in the Panzhihua titanium processing plant. It was found that with the addition of collector， hetero-aggregation was tend to occur between hydrophobized ilmenite and titanaugite particles. Fine titanaugite particles could adhere to the surface of ilmenite and enter into the concentrate products， resulting in the non-selective flotation of titanaugite. After the treatment of high-intensity conditioning， the TiO₂ grade of concentrate increased sharply from 39.97% to 43.79%， while the recovery rate increased from 78.09% to 79.28%. The fluid force field generated by high-intensity conditioning can eliminate the hetero-aggregation between ilmenite and ilmenite particles and strengthen the dispersion state between them. This is the intrinsic reason for high-intensity conditioning to enhance the TiO₂ grade of titanium concentrate.

Key words: ilmenite; titanaugite; flotation; hetero-aggregation; high-intensity conditioning
