摘　　要：硫的包裹是影响锌浸出率的重要因素。本文通过对比实验证明了硫的包裹对锌浸出率的影响,初步探索出了木质磺酸钠影响锌浸出率的机理,以及保证锌回收率的前提下,木质磺酸钠的合适用量。Encapsulation of sulfur is important factors in oxygen pressure leaching of sphalerites.It proves the effect of encapsulation of sulfur on zinc dissolution through contrast experiments,and explores initially the mechanism of the effect of sodium lignosulfonate on zinc dissolution,and the dose of sodium lignosulfonate under the premise of the high zinc dissolution rate.

关 键 词：硫的包裹 木质磺酸钠 锌精矿 氧压酸浸
