摘 要:探讨用硫酸直接浸出氧化铅锌矿,研究各种因素对浸出的影响。结果表明,在最佳工艺条件下,锌的浸出率可达97%以上,铅入渣率可达98%以上,产液速率大于162.5 L/m2·h,渣含锌约2.5%,渣含铅量高达40%以上,浸出渣可送往炼铅系统处理。
Abstract: The direct sulfuric acid leaching process of lead-zinc oxide ore is investigated,and the impact factors on leaching are described.The results show that the more than 97% of zinc can be leached,more than 98% of lead into the slag,the rate of fluid production is greater than 162.5L/m2·h,the zinc content in residue is about 2.5% and the lead content in residue is greater than 40%,under the optimal condition.The leaching residue can be sent to the lead smelting process.
