The invention relates to a method for reducing the firing temperature of a tailing fine-silt-based ceramic material and improving the mechanical property of the tailing fine-silt-based ceramic material by utilizing molybdenum ore tailing fine silt and fluorite ore tailing fine silt, and belongs to the technical field of high-value utilization of vanadium titano-magnetite tailings, magnetite tailings, molybdenum ore tailings and fluorite ore tailings and ceramic preparation. Vanadium titano-magnetite tailings, magnetite tailings, molybdenum ore tailings and fluorite ore tailings are adopted as raw materials, and the ceramic material is prepared through the processes of material mixing, ball milling, forming and low-temperature sintering. The ceramic material prepared from the vanadium titano-magnetite tailings, the magnetite tailings, the molybdenum ore tailings and the fluorite ore tailings has the characteristics of high compressive strength and breaking strength, high volume density, low sintering temperature, simple preparation process and low raw material cost, and can be used for preparing refractory materials, porous ceramics, building materials and the like. The required raw materials are easy to obtain, the preparation process is simple, the utilization rate of the vanadium titano-magnetite tailings, the magnetite tailings, the molybdenum ore tailings and the fluorite ore tailings is high, the production cost is reduced, meanwhile, the problem that the vanadium titano-magnetite tailings, the magnetite tailings, the molybdenum ore tailings and the fluorite ore tailings are accumulated massively and pollute the environment can be effectively solved, and waste is turned into wealth.
