— ABSTRACT. Recently, beneficiation of iron from low-grade ores with high impurities has been a matter of discussion. Flotation is one of the most effective technologies for the upgrading of low-grade, finely grained iron ores.
The flotation tailings of the Donganshan sintering plant contain 22.82% Fe, 9.87% FeO, 51.24% SiO 2 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%.
