摘要
为综合回收利用某含金银多金属氧化矿氰化尾渣中的铁,针对氰化尾渣进行了弱磁选和强磁选回收铁的试验研究.试验结果表明:在弱磁粗选磁场强度为238.85 kA/m,弱磁精选磁场强度为159.24 kA/m,弱磁粗选尾矿强磁选磁感应强度为1 200 mT的条件下,通过弱磁—强磁分选工艺,获得了全铁品位为64.08%、铁回收率为21.11%的弱磁铁精矿和全铁品位为45.81%、铁回收率为40.31%的强磁铁精矿,综合全铁回收率为61.42%,达到了综合回收利用铁资源的目的.
Abstract
In order to comprehensively recycle iron from cyanide tailings in a containing gold silver polymetallic oxide ore,an experimental study on iron recovery from cyanide tailings by low intensity magnet-ic separation and high intensity magnetic separation was carried out.The test results show that under the con-dition that the magnetic field intensity of low intensity magnetic roughing is 238.85 kA/m,the magnetic field intensity of low intensity magnetic cleaning is 159.24 kA/m,and the magnetic induction intensity of high in-tensity magnetic separation of low intensity magnetic roughing tailings is 1 200 mT,the low intensity mag-netic iron concentrate with total iron grade of 64.08%and iron recovery rate of 21.11%and the high intensity magnetic iron concentrate with total iron grade of 45.81%and iron recovery rate of 40.31%are obtained by low intensity magnetic-high intensity magnetic separation process.The comprehensive total iron recovery rate is 61.42%,which achieves the purpose of comprehensive recovery and utilization of iron resources.
