摘　　要：在室内小基础上,通过现场扩大试验,验证了室内小试的相关参数,确定生产工艺流程和相关设施设备,原来不能直接渗滤浸出的矿石,通过制制粒,满足了堆浸的要求,浸出率达到90%以上,通过串联堆浸,与原直接渗滤渗出相比节约硫酸约40%,浸出率提高约15%。Determines production processing and related facility equipment on indoor little-test foundation.Through related parameter on-the-spot.That enlarge experiment and has verified indoor test.originally cannot directly soap to strain the ore that soap rate to reach 90% more.Soak through making contact to pile up.with directly seep to strain seep to compare economize the contract 40% of Sulfuric acid and soak rate raising to ask 15%.

关 键 词：制粒 堆浸 酸法 低渗透
