针对攀西地区追求钒钛铁精矿品质造成选铁尾矿变细,高梯度强磁机难以同时兼顾细粒级钛铁矿品位和回收率的问题,采用高梯度强磁机与悬振锥面选矿机作为浮选原料富集设备,并与浮选组成联合选别工艺进行实验室对比研究。试验表明:设置有悬振作业的浮选原料中干扰浮选的-19μm矿泥含量低于单一强磁作业,且“悬振+浮选”联合流程对TiO_2品位10.57%的细粒级钛铁矿回收效果最优,能获得产率13.29%、TiO_2品位47.20%、TiO_2回收率60.00%的合格钛精矿。
In view of the fact that the quality of vanadium-titanium-iron concentrates in Panxi area is narrowed due to the quality of vanadium-titanium-iron concentrates, it is difficult to balance the grade and recovery rate of fine-grained ilmenite with high-gradient ferromagnetic machines. Flotation concentrator as a raw material enrichment equipment, and flotation composition of the joint sorting process for laboratory comparison. The results show that the content of -19μm slime containing flotation in the flotation raw material with suspension operation is lower than that of a single ferromagnetic operation, and the combination of “suspension vibration + flotation” Ilmenite has the best recovery efficiency, and qualified titanium concentrates with a yield of 13.29%, a TiO 2 grade of 47.20% and a TiO 2 recovery of 60.00% can be obtained.
