Abstract: In order to improve the recovery and utilization rate of resources，improve the plant and its surrounding environment，and realize the energy saving and emission reduction of the plant，in view of the problems that a certain amount of iron resources in the tailings of the plant are not effectively recycled， and a large number of tailings are piled up to pollute the environment and occupy land，the chemical multielement， phase analysis and low intensity magnetic-high intensity magnetic-shaking table test were carried out. The results show that the total iron grade of the tailings is 11.90%，which has the value of recycling. The iron concentrate 1 with total iron grade of 65.72% and iron recovery rate of 14.92% and the iron concentrate 2 with total iron grade of 59.15% and iron recovery rate of 3.59% are obtained through experiments. The test shows that the process can realize the recovery and utilization of iron resources in the tail⁃ ings.
