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 = 75 μm、P80 =150 μm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.
Abstract
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 P80 =75 μm and P80 =150 μm.In the roll bottle leaching tests,the leaching rate of the surface ore was above 70%under an ore particle size of P80 =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 P80 =6 mm and P80 =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.
