Hematite ore was obtained from Changjiang Li Autonomous County, Hainan Province. The chemical composition and XRD pattern of the raw ore are shown in Table 1, and Fig. 1.Iron is the main element to be recovered from the ore, the total iron (TFe) grade was 40.53%, and the FeO content was 4.80%.

hematite, and anatase [10, 11]. During coal mining and washing, about 10–15% of the total coal production is discarded in the form of coal gangue; meanwhile, a certain amount of coal slime with low heat value is also generated. In recent decades, more and more researches focus on the generation of commercial heat and
