摘　　要：研究大冶鑫泰矿业有限责任公司4#矿体含泥氧化铜柱浸工艺过程,优化酸性介质制粒柱浸工艺参数,为现场扩大试验提供技术数据。结果表明,制粒后的粒矿堆高3m,经硫酸喷淋浸出25d,渣计铜浸出率78.02%,硫酸实际酸耗3.57t/t.铜,25d浸出后矿堆仍具有良好的渗透性。In order to optimize the parameters and derive the reference for pilot test, the technology of the acidified granulation pretreatment-head leaching processing of argillious oxidized copper ore from 4^# ore body of Daye Xintai co. Ltd. is investigated. The results show that the copper leaching rate in view of residue is 78.02 % for 25d sulfuric acid solution spray leaching in pelletized ore heap with 3m high. The actual consumption of the sulfuric acid is 3.57t/t-Cu. The permeability of the ore heap is still wetl enough after 25d leaching.
