摘要: 四川某铁矿磁选尾矿中含有一定量的铁矿物和硫矿物可以综合回收。根据该尾矿的矿石性质,采用筛分分级—-0.5 mm重选预富集—重选粗精矿浮选选硫—浮选尾矿磁选选铁的工艺流程进行选矿试验,获得了硫精矿、强磁性铁精矿和弱磁性铁精矿3种产品。硫精矿硫品位和硫回收率分别为39.66%和82.54%,强磁性铁精矿铁品位和铁回收率分别为62.28%和32.59%%,弱磁性铁精矿分别为51.87%和5.36%。

Abstract: Partial magnetic iron minerals and sulfur minerals were contained in a certain Sichuan tailings from iron ore separation.According to the nature of the tailings,beneficiation tests on iron concentration are made by the screening classification- -0.5 mm gravity pre-concentration-sulfur flotation from crude concentrate after gravity separation - tailings flotation magnetic separation process.Three kinds of products like sulfur concentrate,strong magnetic iron concentrates and weak magnetic iron concentrates were got,where Sulfur concentrate is grading at 39.66% at an 82.54% recovery,strong magnetic iron concentrate is grading at 62.28% at a 32.59%% recovery,and weak magnetic iron concentrate grading at 51.87% at a 5.36% recovery respectively.

Key words: Iron tailings, Iron ore, Sulfur minerals, Comprehensive recovery
