Abstract

A process of hydrometallurgical treatment for removing metal impurities from zinc sulfate solution containing Fe+++ ions includes adding to said solution a silicate capable of forming dissolved silicic acid in situ, and a neutralizing base to provide a pH between 1.5 and 4.5. The metal impurities are precipitated as a solid residue on a base of iron silicate. (From CA1115024 A1) [FR2390504A1]
