    Abstract

  • The flotation tailings of the Donganshan sintering plant contain 22.82% Fe, 9.87% FeO, 51.24% SiO2 and a low S and P content of 0.03%, which belongs to low sulphur, low phosphorus and high silicon type iron tailings. In addition, the tailings contain 56.44% of the −0.038 mm particles. Also, the distribution of iron minerals in this size-level was 67.62%. In order to achieve efficient recovery of iron from this tailings, a systematic experimental study was carried out in this experiment using the process of stirred mill grinding - low intensity magnetic - high magnetic roughing - high magnetic selection - reverse flotation. The results showed that a mixed magnetic separation concentrate with a TFe grade of 38.20% and a TFe recovery of 63.51% was obtained at a fineness of −0.038 mm (95%), a magnetic induction of 95 kA/m for the low magnetic separation, high intensity magnetic field strength of 796 kA/m for roughing magnetic separation and high intensity magnetic field strength of 398 kA/m for cleaning magnetic separation. The appropriate reverse flotation conditions for mixed magnetic concentrates were pulp temperature 40 ℃, pulp pH 11.5, starch dosage of 1000 g/t, CaO dosage of 900 g/t, rougher collector TD-2 dosage of 600 g/t, primary cleaning collector dosage of 300 g/t and secondary cleaning collector dosage of 300 g/t. The flotation concentrate with iron grade of 62.34% and iron recovery of 55.10% was obtained by closed-circuit test. The continuous test for complete flow were carried out, the iron concentrate with iron grade of 62.43% and iron recovery of 35.00% was obtained, and the iron grade of comprehensive tailings was 17.01%. The test results can provide guidance for the high-efficiency beneficiation and recovery of iron minerals in the flotation tailings of Donganshan.
