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%。
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.
