| 摘 要： | 含碲金精矿是一种典型的难浸精矿。本文通过多种方案的对比试验，表明金碲精矿先经硝化预处理，然后进行常规氰化浸出，金的浸出率可达９５％以上，氰浸渣经硫化钠浸出，可回收６０％以上的金属碲。

| Abstract: | Tellurium-bearing gold concentrate is typically a kind of refractory gold ore.Through repeated experiments and contrasts among the treatment programs, this paper makes a conclusion that it must have the pretreatment of nitrification for the tellurium-boring gold concentrate prior making conventional cyanide leaching, so the leaching rate can reach to over 95%.Then,the residue is leached by sodium sulfide.The recovery rate of metallic tellurium can reach to 60% or more. |

| Keywords: | tellurium-bearing gold concentrate pretreatment of nitrification sodium sulfide leaching leaching rate |
