Efficient iron recovery from iron tailings using
2021-2-15 Recycling iron tailings is significant for environmental security and resource recovery, as they contain iron-rich minerals. Given the complex composition of iron minerals and the low grade of iron present in the tailings, innovative suspension roasting-magnetic separation (SRMS) technology was proposed to treat iron tailings that would separate out the iron minerals for recovery.

Evaluation of Additional Iron Recovery from Iron Ore
2018-3-27 Wet magnetic separation of Abagur tailings -0.007 mm in size allowed recovery of 0.6 to 1.45% of magnetic fraction with Fe total content of 53.3 and 51.6%, respectively, and Fe mag content of 49.8 and 48.5%. Fitting of modern separators with the magnetic systems based on neodymium–ferrum–boron considerably improves output of the machines (in dry centrifugal separation circuit) and enhances the yield of magnetic product in wet separation of tailings.
