摘　　要：某金矿石金嵌布粒度较细且分布不均匀,主要集中在-0.038 mm,为微细粒金。针对矿石性质,进行了浮选和全泥氰化浸出探索试验研究,最终确定采用全泥氰化浸出工艺流程,取得了良好的选别指标。原矿金品位4.01 g/t,在最佳试验条件下,全泥氰化浸出工艺的金回收率达到84.29%,浸渣金品位为0.63 g/t。该研究为矿石的高效利用提供了技术依据。A flotation and all-sliming cyanide leaching experimental study was conducted on the ores from a gold mine with fine and unevenly distributed gold particles,mainly concentrated in the range of-0.038 mm,known as fine-grained gold.Based on the characteristics of the ores,the all-sliming cyanide leaching process was ultimately adopted,achieving favorable results.The original ore had a gold grade of 4.01 g/t,and under optimal test conditions,the gold recovery rate reached 84.29% through all-sliming cyanide leaching,with a residue grade of 0.63 g/t.This study provides technical basis for the efficient utilization of the ores.
