| 摘 要： | 通过工艺矿物学研究，查明了金川三矿区低品位铜镍矿石的矿物组成、铜镍的赋存形式及主要有用矿物的嵌布特性。研究结果表明：矿石中的铜、镍主要以镍黄铁矿、紫硫镍铁矿、黄铜矿、墨铜矿形式存在，但其他硫化矿物及脉石矿物与它们嵌布关系密切而复杂；矿石蛇纹石蚀变严重，易于泥化。这些将给铜、镍的分选带来不利影响。

| 关 键 词： | 低品位铜镍矿 铜镍赋存形式 有用矿物嵌布特性 矿石蚀变 |

| Abstract: | The process mineralogy study was made to identify the mineral composition, occurrence forms of copper-nickel, and the dissemination characteristics of main minerals in low-grade copper-nickel ores of Jinchuan No.3 deposit. The results showed that copper and nickel ores mainly occurs in form of pentlandite, violarite, chalcopyrite and wallerite, but other sulfides and gangues have close and complex dissemination relation with these minerals. Serpentine has a critical argillic alteration, which brings unfavorable effect on the separation of copper and nickel. |
