Zinc ferrite dissolution behavior in acid leaching
2026
Overview
ZnFe 2 O 4 is a significant byproduct of the zinc metallurgical process. Research on its recovery and utilisation has been shown to reduce resource waste and play a positive role in achieving comprehensive resource utilisation in the zinc metallurgical process. This study utilised a piecewise interpolation method to calculate the zinc leaching rate of pure zinc ferrite under specific experimental conditions. This approach was informed by previous acid leaching data for pure zinc ferrite and zinc calcine. A comparative analysis was conducted on the Zn and Fe leaching rates from zinc ferrite within zinc calcine under identical experimental conditions. The objective of this analysis was to identify suitable conditions for preparing and purifying zinc ferrite. The findings suggest that zinc ferrite products can be effectively separated and purified under conditions of acid concentration levels greater than 120 g/L, leaching temperature of 75 °C, and leaching time from 150 minutes to 180 minutes; or an H 2 SO 4 concentration greater than 200 g/L, an ambient leaching temperature at 75 °C, and a leaching time from 60 minutes to 90 minutes.
