producing high-grade iron ore sinter feed. In the literature, African iron ore types are graded as low-grade (60.0–62.9% Fe; 8.6– 12.5% SiO 2 and insolubles), high-grade (66.0– 69.9% Fe; 0.8–4.5% SiO 2 and insolubles), and meduim-grade as the remaining portion (Astrup et al., 1998). The low-grade ore used in this work contains less than 60% Fe.

Beneficiation of a low-grade, hematite-magnetite ore in China

In China, most reserves of rich iron ores have now been depleted and sustainable development of low-grade iron ores has become a critical discussion topic in the mining industry today. The aim of this study was to evaluate the applicability of beneficiating a low-grade, hematite-magnetite ore (assaying 18.64% Fe) for subsequent utilization.

Flotation, on the other hand, is used to reduce the content of impurities in low-grade iron ores [1-2,5]. Iron ores can be concentrated either by direct anionic flotation of iron oxides or reverse cationic flotation of silica, however reverse cationic flotation remains the most popular flotation route used in the iron industry [5,7].
