摘　　要：对老挝某金矿进行工艺矿物学研究,通过化学分析、金物相分析、光学显微镜、扫描电镜等手段,查明了金在矿石中的赋存状态、嵌布特征、金矿物形貌、游离金在矿石中的分配等特征,基于此研究制定了全泥氰化提金工艺流程,并得到后续选矿工艺试验验证,可更好指导矿山现场生产,为东南亚地区类似金矿回收提供经验及理论依据。In this paper,the process mineralogy of gold ore from Lao is studied by means of chemical analysis,gold phase analysis,light microscope and SEM. The characteristics such as occurrence and dissemination characteristics of gold,gold mineral morphology,the distribution of free gold and inclusion gold in ores have been ascertained. Based on this research,all-slime cyanidation process has been designed,which was authenticated by subsequent benefication process test and can direct mine production better. This study should provide empirical theoretical basis for the recovery of similar gold mines in Southeast Asia.
