Abstract: A multi-source solid waste recycling method based on composition design for calcium-silicon-aluminum-magnesium oxide includes collecting multi-source solid waste composition data; calculating and designing compositions of calcium oxide, silicon oxide, aluminum oxide and magnesium oxide units to obtain an inorganic non-metallic raw material with a target composition; and melts the raw material into slag, and uses carbon, metallic aluminum, aluminum nitride, aluminum carbide, silicon nitride and silicon carbide in the multi-source solid waste as reducing agents. The slag provides a high-temperature homogeneous reaction environment and serves as a “solvent” for reactants, the reducing agents reduce valuable metals in the slag to obtain an alloy, thereby achieving recovery of the valuable metals, and the slag is used for the inorganic non-metallic material in a high-value mode.
