摘要
用氧化锌矿作原料经酸浸、净化和焙烧可制得纯度为98.3％的活性氧化锌,工艺简单。研究了酸浸温度、pH值对锌浸出率的影响,考察了净化工艺中的除杂问题,并用DTA分析了活性氧化锌制备过程中焙烧工艺的影响。
Activated zinc oxide is prepared by using zinc oxide ores as raw material through acid-leaching.purification and calcination operations. Effects of acid-leaching temperature and pH value on zinc leaching rate are studied. The impurities removal in the purification process and the effect of calcination process on preparation of activated zinc oxide are also examined.
