Abstract: Recycling iron tests on an iron tailing was conducted, according to characteristics of iron tailing from a old iron mine. Iron concentrate with yield of 22.12%, iron grade of 58.90%, iron recovery of 64.31%was obtained with the process of step grinding—low intensity magnetic separation + fine screening—high intensity magnetic separation—gravity separation, which provides a technical basis for development and utilization of this type of tailings.
