摘　　要：山东某金尾矿金品位为0.87 g/t,金主要集中微细粒级。矿物颗粒中的金以自然金和银金矿形式存在,分别占总金的56.33%和43.67%。为确定合适的回收工艺,进行了选矿试验研究。结果表明:采用2粗2精2扫流程处理试样,可获得金品位为8.50 g/t、回收率为56.69%的金精矿,尾矿金品位降至0.40 g/t。The gold grade of a gold tailings is 0.87 g/t in Shandong.The gold is concentrated in fine-grained grades.The gold in the mineral particles exists in the form of natural gold and silver gold,which account for 56.33%and 43.67%of the total gold,respectively.In order to determine the appropriate recycling process,beneficiation test was conducted.The results show that the gold concentrate with gold grade of 8.50 g/t and recovery of 56.69%can be obtained by using two roughing two cleaning two scavenging process,and the gold grade of tailings is reduced to 0.40 g/t.
