Preparation of feed Zinc Sulfate with one Water from Zinc Residue |
PENG Li xin (Hunan Building Material College; Hengyang 421008; China) |
Abstract:The zinc sulfate with one water was produced from zinc residue by the way of acid leaching. Most iorn could be removed by oxidizing and the copper and cadmium could be exchanged by excessive zinc powder. The production impurity is over 98%. This technology process has the advantage of working facillity, leaching quickly and less expensive. |
Key words:zinc residue; acid leaching; zinc sulfate with one water |
