Roasting technology is increasingly used in the beneficiation of refractory iron ores. During the roasting process, the presence of pyrite in some iron ores leads to the formation of SO 2, requiring effective sulfur fixation techniques.This study proposed an innovative in-situ sulfur fixation method by pre-oxidation roasting, in which sulfur was …
Five kinds of iron ore, return ore, limestone, dolomite, coke and quick lime were used in the experiment. All components are divided by rotary screen to ensure uniformity before mixing, and the mass fraction of each component is shown in Table 1.In the three cases studied in this paper, the mass fraction of quick lime is 0%, 1%, and 2%, …
