摘要: 唐钢冶金尘泥含有较多粒度在0.05~0.08 mm的单晶铁矿物,为高效开发此二次资源,采用新型、高效、细粒重选设备——悬振锥面选矿机进行了铁回收试验。结果表明,用LXZ-1200A型悬振锥面选矿机处理试样,在给矿浓度为20%,分选面转动速度为1.2 r/min,盘面振动频率为385次/min,给矿量为0.35 t/h,冲洗水流速为1.08 m3/h情况下,可获得铁品位为56.79%、铁回收率为61.23%的重选铁精矿。一次重选获得这样的富集效果,表明悬振锥面选矿机适合于冶金尘泥的开发利用。

Abstract: Metallurgy dust contains a lot of single-crystal iron minerals with granularities in 0.05~0.08 mm in Tangshan Iron and Steel Group.In order to high efficiently develop these secondary resources,iron recovery tests have been carried out with new and high efficient,fine grained optional equipment-suspended vibration cone concentrator.Results indicated that iron concentrate with iron grade of 56.79% and recovery of 61.23% was obtained by using LXZ-1200A type of suspension vibration cone concentrator,when the feeding density was 20%,and rotation speed was 1.2 r/min,the vibration frequency of disk was 385 per minute,the feeding capacity was 0.35 t/h,the flow rate of flushing water was 1.08 m3/h.Good enrichment results can be obtained through once gravity separation,revealing that suspended vibration cone concentrator is suitable for development and utilization of metallurgical dust.
