摘要
对黔西南某微细浸染型金矿开展了浮选试验研究,初步探索了浮选法提金的较优工艺条件。在磨矿细度-0.075 mm粒级占73.17%,丁基黄药与丁铵黑药配比为4∶1、总用量为100 g/t,活化剂硫酸铜用量200 g/t,起泡剂2~#油用量80 g/t条件下,采用一粗一精一扫闭路浮选流程,可得到金品位2.11 g/t、回收率39.28%的金精矿。
Flotation tests were conducted to recover gold from a fine disseminated gold deposit in southwestern Guizhou Province,and processing parameters were roughly optimized.It is shown that a closed-circuit flotation flowsheet consisting of one roughing,one cleaning and one scavenging with grinding fineness of-0.075 mm 73.17%,dosage for activator copper sulfate,frother 2^#oil and collector,a mixture of butyl xanthate and butylamine dithiophosphate（4∶1）,respectively,at 200 g/t,80 g/t and 100 g/t,produced a final gold concentrate grading 2.11 g/t Au at 39.28%recovery.
