摘　　要：某厂湿法炼锌系统中由于铜回收率偏低,影响了有价金属的综合回收水平。通过将原有的低酸浸出—中和工艺改为二段高酸浸出—中和沉矾工艺后,铜回收率提高了20个百分点左右。The copper recovery of a zinc hydrometallurgy plant was low,affecting the comprehensive recovery of valuable metals.The recovery rate of copper is improved by about 20 percent point after the process transformation from 'low acidity leaching,neutralization' to 'two-step high acidity leaching,neutralization jarosite process'.

关 键 词：湿法炼锌 铜回收 高酸浸出 中和沉矾
