摘　　要：通过探究湿法炼锌浸出过程中浸出温度、浸出时间、pH值等因素对渣锌含量的影响,总结出了最佳的工艺条件:在75℃、pH=1.5连续浸出4 h,渣锌含量为3.11%,其中可溶锌含量为1.02%,比原工艺渣含锌量降低1.05%,可溶锌含量降低1.01%。The effect on zinc content of the leaching temperature,leaching time,pH value and the other factors in zinc hydrometallurgy leaching process is explored,therefore the optimal process conditions are summarized:under 75℃,the pH value equal to 1.5,and continuous leaching for 4 hours,the zinc content in residues is 3.11%,the soluble zinc content is 1.02%,which is lowered by 1.05%than the zinc content in residues in the original process,and the soluble zinc content is reduced by 1.01%.
