哈尔滨某选铜尾矿综合回收石榴石试验研究

摘要

A copper tailing contained calcium and iron garnet.The two combined technological flowsheet of low -intensity magnetic separation and high -intensity magnetic separation and gravity concention by tabling and low - intensity magnetic separation were compared.Using the better flowsheet of gravity separation by tabling and low -intensity magnetic separation, calcium and iron garnet concentrate of 98％ with a recovery of 90％ and iron concentrate of 68.0％ TFe and 2.28％ S were obtained.This laid a good foundation for industrial utilization and the maximum benefit.%某选铜尾矿中伴生钙铁石榴石,比较了弱磁-强磁联合试验、重选(摇床)-磁选联合试验工艺流程,后者效果较好,可获得纯度为98%、回收率为90%的钙铁石榴石精矿及含TFe、S分别为68.0%、2.28%的铁精矿(含硫较高),为其工业利用、企业效益最大化奠定了基础.
