对云南某贫硫化物稀疏浸染型金矿石进行了提金试验研究。其结果表明:氰化工艺不适宜处理该类矿石;采用原矿重选浮选闭路工艺流程,可获得重选精矿金品位464.20 g/t,金回收率30.95%,浮选精矿金品位66.32 g/t,金回收率57.60%,总回收率88.55%的良好指标。

Experimental research has been carried out to gold extraction from one loosely disseminated gold ore with little sulfide .The results show that cyanidation is not suitable for such ores .But raw ore gravity separation-closed circuit flotation process achieves satisfactory results ,with gravity separation gold concentrate grade of 464.20 g/t,gold recovery rate of 30.95%;flotation gold concentrate grade of 66.32 g/t,gold recovery rate of 57.60%,total recovery rate of 88.55 %.
