摘要
介绍了利用硫酸浸取含锌废渣 ,通空气氧化除铁 ,加稍过量锌粉置换除铜镉 ,制备主含量≥ 98% ,杂质含量符合要求的饲料级一水硫酸锌的方法。其方法具有浸出时间短、操作方便、生产成本低。
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.
