After iron tailings was subjected to preconcentration followed by magnetizing roasting process, the obtained product was taken in an experiment to be processed respectively by adopting a grinding and magnetic separation process and a combined process of grinding plus magnetic separation followed by flotation process. The roasted ore with TFe grade of 33.19% was processed using a grinding and magnetic separation approach, resulting in an iron concentrate grading 63.04% TFe at 80.04% recovery at a grinding fineness of -0.025 mm 97%. Although the processing flowsheet is simple, it is still hard to achieve such a grinding fineness in commercial practice and the grinding cost is also extremely high. However, a process consisting of grinding, magnetic separation and flotation, with a grinding fineness of -0.025 mm 85%, can produce an iron concentrate grading 65.36% TFe at 73.39% recovery. Therewith, such grinding fineness is commercially practicable and the grinding cost can be obviously reduced.

对某尾矿经预富集-磁化焙烧后的产品分别进行了磨矿-磁选和磨矿-磁选-浮选联合工艺试验研究。TFe品位33.19%的焙烧矿采用磨矿-磁选工艺,在磨矿细度-0.025 mm粒级占97%时可获得TFe品位63.04%、回收率80.04%的铁精矿,虽然工艺流程简单,但磨矿细度在工业生产中较难实现,且磨矿成本极高;采用磨矿-磁选-浮选联合工艺,在磨矿细度-0.025 mm粒级占85%时可获得TFe品位65.36%、回收率73.39%的铁精矿,且磨矿细度在工业生产中可以实现,磨矿成本明显较低。

对某尾矿经预富集-磁化焙烧后的产品分别进行了磨矿-磁选和磨矿-磁选-浮选联合工艺试验研究。TFe品位33.19%的焙烧矿采用磨矿-磁选工艺,在磨矿细度-0.025 mm粒级占97%时可获得TFe品位63.04%、回收率80.04%的铁精矿,虽然工艺流程简单,但磨矿细度在工业生产中较难实现,且磨矿成本极高;采用磨矿-磁选-浮选联合工艺,在磨矿细度-0.025 mm粒级占85%时可获得TFe品位65.36%、回收率73.39%的铁精矿,且磨矿细度在工业生产中可以实现,磨矿成本明显较低。

After iron tailings was subjected to preconcentration followed by magnetizing roasting process, the obtained product was taken in an experiment to be processed respectively by adopting a grinding and magnetic separation process and a combined process of grinding plus magnetic separation followed by flotation process. The roasted ore with TFe grade of 33.19% was processed using a grinding and magnetic separation approach, resulting in an iron concentrate grading 63.04% TFe at 80.04% recovery at a grinding fineness of -0.025 mm 97%. Although the processing flowsheet is simple, it is still hard to achieve such a grinding fineness in commercial practice and the grinding cost is also extremely high. However, a process consisting of grinding, magnetic separation and flotation, with a grinding fineness of -0.025 mm 85%, can produce an iron concentrate grading 65.36% TFe at 73.39% recovery. Therewith, such grinding fineness is commercially practicable and the grinding cost can be obviously reduced.
