在对沂南金矿铜井矿点的尾矿进行矿物学分析的基础上,采用弱磁-强磁-重选联合工艺流程回收尾矿中的有价元素铁,最终得到铁品位、产率、铁回收率分别为63.21%、0.33%、2.67%的铁精矿和34.66%、1.72%、7.64%的含铁产品。
Based on the mineralogical analysis of the tailings of Tongjing Mine in Yinan Gold Mine, the valuable elemental iron in the tailings is recovered by the combination of weak magnetic-ferromagnetism-gravity reselection process, and finally the iron grade is obtained. The yield , Iron recovery rates were 63.21%, 0.33%, 2.67% of iron concentrates and 34.66%, 1.72%, 7.64% of iron products.
