Abstract Scope In China's Inner Mongolia Tuquan County 1.4 billion tons of reserves of serpentine deposits were found. Because serpentine belongs to magnesium silicate, there is no good reducing agent to reduce magnesium. In the local there is also a large reserves of high-aluminum bituminous coal for thermal power, power plants each year produce a large number of high-aluminum fly ash. The aluminum-silicon alloys obtained from this high-aluminum fly ash as the raw material by carbothermal reduction method can reduce the magnesium from the serpentine. In this paper, first, the feasibility of producing aluminum-silicon alloys by carbothermal reduction of high-alumina fly ash was studied, the hypereutectic aluminum-silicon alloys were obtained; and then the investigation on aluminum-silicon alloy as a reducing agent to reduce of metal magnesium from serpentine was carried out. According to the previous investigation, the optimized technical process for the extraction of metal magnesium from serpentine was proposed.
