Abstract

Abstract

Steelmaking slags containing large amounts of Ca silicate is a potentially alkaline waste that can be used to capture CO₂ to synthesize high-quality CaCO₃. Here, effect of ultrasonic on leaching efficiency and selective leaching rate of Ca in steelmaking slags was studied in acetic acid solution. Experimental results shown that ultrasound could help to strengthen leaching of Ca in acetic acid solution. Ultrasonic power, liquid-solid ratio, and initial acetic acid solution concentration were positively correlated with Ca extraction, but particle size of steelmaking slags and temperature were negatively correlated with Ca extraction. Meanwhile, temperature and initial concentration of acetic acid solation had a negative correlation to selective extraction yield of Ca, which were beneficial for the diffusion of impurity elements. Also, ultrasonic power and solid to liquid ratio were insignificant effect to selective extraction yield of Ca, but increase of ultrasonic power and solid to liquid ratio were also helpful to the diffusion of impurity elements. It was worth noting that decreasing grain size of steelmaking slags would raise selective leaching efficiency of Ca and the maximum selective leaching rate upped to 96.7%. During leaching process, ultrasonic could effectively break and remove the porous passivation layer formed by residual silica on surface of steelmaking slags particles, and improved leaching rate of Ca.
