从锌渣中回收锌盐产品的提纯工艺研究

目前，酸溶法从锌渣中回收的锌盐产品质量很差。采用本研究浸取、氧化、置换为主的提纯工艺，可从工业锌渣中回收质量很好的以硫酸锌为主的锌盐系列产品，实践证明所耗费用不到产品价值的一半，新生废物可回用于电镀生产。

Purification Technology's Study on Recovering Zircate from Zinc Residue

Nowadys, the quality of recovered zircate from zincresidue by acid dissolving was very poor. By adopting the purification technology mainly being of lixiviation, oridtion and displacement, it could recover well-qualitative serial zincate being main of zinc sulfate from zinc residue. In real production, the total consumption was under half of the product's value. The new-made residue could be used in electroplating again.
