Abstract: The present disclosure provides a method for producing value-added by-product yellow phosphorus slag through an unconventional electric furnace process, derived from yellow phosphorus. This method is related to the technical field of comprehensive utilization of mineral resources. The disclosed method involves the following steps: mixing mid-low-grade phosphate rock, silica, coke, and a cosolvent to create a blended material, subjecting the blended material to high-temperature reduction in a yellow phosphorus electric furnace to yield yellow phosphorus and water-quenched slag, and then drying the water-quenched slag using yellow phosphorus tail gas to obtain the yellow phosphorus slag. According to this disclosure, a P2O5—CaO—SiO2—MgO—R multi-component system is established using the blended material.
