摘要
某微细粒难处理金矿石有价元素金品位为2.75 g/t,其主要载金矿物黄铁矿嵌布粒度较细。针对矿石性质,开展了选矿试验研究。结果表明:在磨矿细度-0.074 mm占84.96%时,采用碳酸钠、水玻璃和硫酸铜作为矿浆调整剂,Y-89和丁铵黑药作为组合捕收剂,MIBC作为起泡剂,闭路试验可获得较好指标,金精矿金品位31.61 g/t、金回收率81.39%。
The gold grade of a micro-fine particle refractory gold ore is 2. 75 g/t. Pyrite,its main gold-bearing mineral,is embedded in fine particles. Experimental research on the dressing of the ore has been conducted according to its property. The results show that with the grinding fineness of 84. 96 %-0. 074 mm,and Na_2CO_3,sodium silicate and CuSO_4 as modifiers,Y-89 and ammonium butyl aerofloat as the combined collector,and MIBC as the frother,the closed circuit can obtain good index that the gold grade of the gold concentrates is 31. 61 g/t and the gold recovery rate is 81. 39 %.
