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.
