A novel route to comprehensive utilization of valuable elements such as Ti, Al, Si and Mg in Ti-bearing electric arc furnace molten slag (Ti-bearing EAF slag) was proposed in this work. The route can be expressed as a three steps process including alkali fusion, water leaching and acidolysis. Following these processes under the optimum conditions, the recovery ratios of TiO2, Al2O3, SiO2 and MgO were about 97.5%, 93.5%, 27.9% and 53.5%, respectively. Meanwhile, nanostructured TiO2, NaA zeolite and Mg(OH)2 fire retardant were synthesized simultaneously by using Ti-bearing EAF slag as raw materials. In addition, the photocatalytic activity of prepared nanostructured TiO2 and the adsorption property of obtained NaA zeolite were investigated. The results showed that the photodegradation efficiency of as-prepared TiO2 was 80% for Rhodamine B and the adsorption efficiency of NaA zeolite was 61% for Cu2+ under the optimum conditions.
