Study and Application of Magnesium Removal Technique in Zinc Hydrometallurgy

Abstract:

Mg²⁺ removal technique in Zn hydrometallurgy was investigated in a single-factor-based test to examine the impact of NaF dose, pH, reactive duration and the reactive temperature on NaF-based Mg removal and the optimal process condition for NaF-based Mg removal was obtained as below: at the actual NaF dose 0.8~1.0 times as much as the theoretical dose, pH 4.0~4.5, reactive duration of 60~75 mins and the reactive temperature 60~75 °C, the agitation rpm of 400. The up to 85.5% of all Mg can be removed, which can be referenced in any experiment at a pilot-plant scale.
