摘　　要：对铋碲精矿的处理 ,传统的方法是火法冶炼。采用湿法冶金工艺 ,直接分离并回收铋碲 ,在国内尚未见报道。试验以某地浮选产出的铋碲精矿为原料 ,采用氧化浸出—还原—置换的湿法分离回收工艺 ,获得铋碲产品总回收率分别为 96.93%和 81.70 % ,达到了分离提取的目的 。The processing method for bismuth-tellurium concentrate was pyrometallurgy traditionally.Direct separation and recovery of bismuth and tellurium by hydrometallurgical technique have not reported in China′s literatures.The experiment described in this paper adopted a bismuth-tellurium concentrate as raw feed,and used a hydrometallurgical separation and recovery technique which basis on oxidizing leaching-reduction-cementation.Experimental results indicate that the recoveries of bismuth and tellurium are 96.93% and 81.70% respectively.
