In view of the problem of degradation of salt product quality of the accompanying elements including Ca, Mg, NH₄⁺? and SO^2?_?4 in the head ash water washing-evaporation crystallization process of the steel metallurgy sinterer, the influence of multi-factor regulation on the migration behavior of accompanying elements is investigated. The results show that when the water-cement ratio is 3mL/g , the water-washing temperature is 25 °C , the water-washing time is 1h and the stirring intensity is 200r/min , the dissolution efficiency of the accompanying elements is significantly improved, and the purity of KCl and NaCl in crystalline salt products can be effectively improved. This study clarifies the correlation between the water-washing parameters and the separation efficiency of impurity elements, and provides a theoretical basis for the preparation of high-purity salt products during the head ash resource of the sinterer.
