Study on Recovering Iron Concentrate from Flue Slime of Meishan Blast Furnace

Through the analysis and study of the utilization of flue dust of blast furnace both in and outside China and in combination with the properties, characteristics and present conditions of the flue slime of Meishan blast furnace, a suggestion was made of recovering iron concentrate from the flue dust using a beneficiation technology consisting of both low intensity and high intensity magnetic separation. The laboratory test achieved good technical and economical results, reaching the expected effect. The technology can be applied in production and popularized.
