| 摘 要： | 某金矿中金的品位为5.20 g/t,为查明该金矿中金的赋存状态,运用传统的光学显微镜以及MLA等大型先进的仪器对该金矿进行了详细深入的研究。结果表明:矿石中91.22%的金赋存于自然金中;另有8.37%的金赋存于碲金矿、碲铜金矿、碲金银矿以及碲银矿(含Au)中,由于这些碲化物在氰化浸出的过程中难以被浸出,所以通过氰化浸出回收这部分金难度较大。

| Abstract: | The gold grade of a gold mine is 5.20 g/t.In order to define the gold occurrence state,the systemic research is carried out with instruments such as traditional microscope and large advanced MLA.The result shows that about 91.22% of gold occurring in natural gold,and about 8.37% of gold occurring in calaverite,bessmertnovite,petzite and hessite.Due to the characteristic of difficult leaching of telluride minerals,this part of gold is difficult to be leached with cyanide. |
