The invention discloses a method for synergistically preparing ferrosilicon alloy and glass-ceramics from photovoltaic waste slag and non-ferrous metal smelting iron slag, and belongs to the technical field of collaborative resource utilization of various smelting slag areas. According to the method, the zinc rotary kiln slag and a reduction tempering agent are subjected to batching, mixing and high-temperature melting to form a reduction-state iron-containing material. The iron-containing material and the silicon slag are further subjected to mixed melting, water quenching and sorting to obtain the ferrosilicon alloy and residual waste slag. The residual waste slag is subjected to tempering, melting, molding, annealing and heat treatment to obtain the glass ceramics. According to the method, the ferrosilicon alloy and the glass ceramics are prepared from the silicon slag and the zinc rotary kiln slag, and a collaborative resource utilization target of the regional smelting slag is achieved. The ferrosilicon alloy is obtained through high-temperature reduction of the zinc rotary kiln slag and chemical combination of the zinc rotary kiln slag and the silicon-rich silicon slag. Because the high-temperature decomposition of silica is not involved, the process greatly reduces the energy consumption, saves the cost and is suitable for industrial popularization and application.
