| 摘要 |
<p>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.</p> |
