Abstract

Language:

The application of D2EHPA in zinc solvent extraction has extensive background. To utilize it more effectively, response surface methodology was used to optimize the concentration condition of zinc pregnant solution (ZPL) extracted by D2EHPA. The research considered zinc, iron, and manganese extraction along with the separation factor of zinc-iron (Sf (Zn-Fe)) and zinc-manganese (Sf (Zn-Mn)) as response variables. The optimal ZPL conditions extracted with 30% D2EHPA as the extraction solvent were as follows: Zn 21.96 g/L, Fe 382.57 g/L, Mn 1 g/L, Sf (Zn-Fe) 8.26, and Sf (Zn-Mn) 1259.82. Additionally, it was found that iron and manganese concentration were the most effective factors affecting zinc and manganese extraction, respectively.
