摘 要: | 对某地金矿石进行系统工艺矿物学研究。矿石含金6.45 g/t,其中金多以次显微金形式产出,金的主要载体矿物是黄铁矿,然而黄铁矿的嵌布粒度很细,尤其是微细粒黄铁矿的占有率高达35.35%,研究表明该矿石为难处理金矿石。

关 键 词: | 次显微金 微细粒 黄铁矿 难处理 |

Abstract: | Process mineralogical research on a gold ore is carried out.The result shows that the gold content is 6.45g/t,existing mainly in submicroscopic gold,and the main carrier mineral is pyrite.The dissemination size of pyrite is so fine that 35.35% is micro-fine.Research results show it is a refractory gold ore. |

Keywords: | submicroscopic gold micro-fine pyrite refractory |
