Abstract: After analyzing the properties,chemical composition of the flue slime from the blast furnace in Tangshan Iron & Steel Company,the paper proposed the suggestion of recovering valuable elements from flue slime by combining process of mineral and metallurgy.The laboratory test results showed that the iron concentrate with the iron grade 53.25% and recovery of 51.05% by tabling gravity separation as well as the carbon concentrate with fixed carbon content of 74.21% and recovery of 66.39% by once rough separation and two times cleaning separation were obtained.The addition of sulfuric acid to the final flotation tailings,the leaching rate of zinc is 97.85%.When the dosage of sodium sulfide is 200kg/t,the recovery of zinc concentrate can reach to 86.36%.
