对广西某原生金矿石进行了选矿试验研究。通过对浮选工艺条件进行对比研究，得出了粗选最佳操作条件：磨矿细度-0.075mm占70%，药剂用量为活化剂CuSO4200 g/t，Na2CO3500 g/t，水玻璃500 g/t，捕收剂丁基黄药60 g/t，丁基铵黑药30 g/t，起泡剂2#油30 g/t。在此最佳条件下进行一次粗选、两次精选、两次扫选试验室闭路试验，可获得金精矿品位为34.00×10-6、金回收率为81.19%的良好指标。

The ore-dressing tests for a native gold ore in Guangxi Province were performed.And by the comparative study of flotation process conditions,the optimum operating conditions of rougher flotation were achieved,which include that:the grinding fineness was-0.075 mm which accounted for 70%,the copper sulfate is 200 g/t,the sodium carbonate is 500 g/t,the water glass is 500 g/t,the butyl xanthate is 60 g/t,the ammonium dibutyl dithiophosphate is 30 g/t,and the 2#oil is 30 g/t.Under the optimal conditions,the closed-circuit tests which are one-stage roughing,two-stage cleaning and two-stage scavenging were performed.Then the gold with the grade of 34.00×10-6 and the recovery of 81.19% can be obtained.
