中文摘要: 利用某铅冶炼厂产生的烟灰，以硫酸为浸取剂，采用适当的添加剂使Zn浸出率达到99％，经除杂净化、碳酸氢铵沉淀制取了纯度大于98％的氧化锌，同时浸渣含Pb达到40％以上，可作为炼铅原料。考察了硫酸浓度、添加剂种类及加入量、温度等对浸出率的影响。
Abstract:The zinc ash of lead refinery is used as raw material and vitriol as leaching agent,the zinc leaching rate is 99%,then the zinc oxide with >98% purity is made by ammonium bicarbonate precipitation process.The following factors on the zinc leaching rate are discussed n detail: sulfuric acid concentration,additive and temperature,etc.
