鋅焙砂一般采用中性-低酸-高酸三段浸出工序，該工藝在酸浸出中浸渣的過程中，鐵也大量浸出進入到溶液中，加重了凈化電積前除鐵的負擔。通過將傳統鋅濕法冶金工藝與氧壓酸浸新工藝相結合，研究了氧壓酸浸處理中浸渣的氧氣壓力、硫酸濃度、溫度、浸出時間、粒度、液固比和分散劑等相關因素的影響。實驗結果表明該工藝不僅提高了鋅的浸出率（>98%），降低了鐵的浸出率（<50%），縮短了生產周期，降低了生產成本，具有良好的經濟效益;而且還具有環境友好和資源利用率高等優點，實現了簡化工藝和節能減排的目的，為工業化生產提供了參考。

Zinc calcine leaching process by three stage，there are neutral leachinglow acid leachinghigh acid leaching.Iron would be leaching into the solution in the process of acid leaching which would increase the difficulty of remo ving iron before electro deposition.In this paper，the traditional zinc hydrometallurgical〖JP+1〗 and oxygen pressure leaching were combined.the effect of oxygen pressure、concentration of sulfuric acid、temperature、leaching time、m ineral particles size、liquor/solid ratio and amount dispersing agentwere found out from the research on oxidizing pressure leaching the residues from the neutral leaching process.The results showed thatoxidizing pressure leaching have good economic benefit and social effect.It is not only improve Zn leaching rate（over 98%），reduce Fe leaching rate（low 50%），shorten production cycle and reduction in production costs，but also environment friendly and raising resource utilization.So as to simplify process and save energymeanwhile it can offered reference for industrial study in future.
