摘　　要：为探索苏丹某金矿床矿石的浸出特性,对其进行工艺矿物学研究,并使用环保浸金剂JC对4个不同深度矿样进行了搅拌浸出、滚瓶浸出及柱浸试验。搅拌浸出试验中,在矿石粒级P80=75μm、P80=150μm条件下,不同深度矿石的浸出率均分别在90%和85%以上;滚瓶浸出试验中,在矿石粒级P80=4.5 mm条件下,表层矿石的浸出率在70%以上,深层矿石的浸出率不足50%;柱浸试验中,在矿石粒级P80=6 mm、P80=10 mm条件下,表层矿石的浸出率分别在55%和65%以上,深层矿石的浸出率分别不足40%和30%。试验结果表明:该矿床表层矿石具有一定的堆浸可行性,而深层矿石适合搅拌浸出工艺。In order to explore the leaching characteristics of ore from a gold deposit in Sudan,process mineralogy studies were conducted,and 4 ore samples from different depth were subjected to agitation leaching,roll bottle leach-ing,and column leaching tests using environmentally friendly leaching agents.In the agitation leaching tests,the leach-ing rates of ores from different depth were above 90%and 85%respectively under ore particle sizes of P 80=75μm and P 80=150μm.In the roll bottle leaching tests,the leaching rate of the surface ore was above 70%under an ore particle size of P 80=4.5 mm,while the leaching rate of the deep ore was less than 50%.In the column leaching tests,the leaching rates of the surface ore were above 55%and 65%respectively under ore particle sizes of P 80=6 mm and P 80=10 mm,while the leaching rates of the deep ore were less than 40%and 30%respectively.The results indicate that the surface ore of this deposit has a feasible heap leaching potential,while the deep ore is suitable for the agitation leaching process.
