Abstract Scope In magnetite powder and coke powder mixed grinding, the surface of the magnetite is covered by carbon, we call it mechanical carbon coating. In this paper, the effect of carbon coating on the reduction of magnetite in H2 was studied. The samples were characterized by field emission scanning electron microscopy, X-ray diffraction and nitrogen adsorption. The results show that, with the increase of the reduction time, the reduction degree and the metallization rate of the magnetite powder are correspondingly increased. When the reduction time was 120 min, the degree of reduction after carbon coating was increased by 39% and the metallization rate was increased by 52%. The samples obtained after the carbon coating had more pores, had a larger specific surface area, had a looser structure. Under the same conditions, carbon coating can increase the reduction rate of magnetite, reduce the reduction time, and is conducive to energy conservation and reduce consumption.
