为了提高秘鲁某铜钼矿石的利用率，针对矿石的物质组成、矿物赋存状态等进行了
详细的工艺矿物学研究。结果表明：矿石中可回收元素 Cu 含量为 0.65%，其中 96.92% 的铜以硫化
物形式存在，矿石 Mo 含量为 0.01%，其中 91.00% 的钼呈辉钼矿产出；矿石中铜矿物为中细粒不均
匀嵌布、辉钼矿为微细粒均匀嵌布、黄铁矿为中粗粒不均匀嵌布。推荐选矿流程：-0.075 mm 占
50% 磨矿细度条件下进行铜钼硫的混合浮选作业综合回收包括铜矿物、黄铁矿和辉钼矿在内的全
部金属硫化物，然后对混合浮选精矿进行铜硫分离作业分别得到铜精矿 1 和硫精矿 1 产品；之后对
硫精矿产品细磨至-0.075 mm 占 65% 再次进行铜硫分离作业获得铜精矿 2 和最终硫精矿产品；将
铜精矿 1 和铜精矿 2 混合成综合铜精矿产品，然后对其进行铜钼分离作业，最后获得最终铜精矿和
钼精矿产品。
In order to improve the utilization rate of a copper-molybdenum ore in Peru, a detailed pro⁃
cess mineralogy study was carried out on the material composition and mineral occurrence state of the ore.
The results show that the recoverable element Cu content in the ore is 0.65%, of which 96.92% of copper ex⁃
ists in the form of sulfide, and the Mo content in the ore is 0.01%, of which 91.00% of molybdenum is molyb⁃
denite. The copper minerals in the ore are unevenly embedded in medium-fine particles, molybdenite is
evenly embedded in micro-fine particles, and pyrite is unevenly embedded in medium-coarse particles. The
recommended beneficiation process is as follows: the mixed flotation operation of copper, molybdenum and
sulfur is carried out under the condition of -0.075 mm 50% grinding fineness to comprehensively recover all
metal sulfides including copper minerals, pyrite and molybdenite, and then the copper and sulfur separation
operation is carried out on the mixed flotation concentrate to obtain copper concentrate 1 and sulfur concen⁃
trate 1 products respectively. After that, the sulfur concentrate product was finely ground to -0.075 mm ac⁃
counting for 65%, and the copper-sulfur separation operation was carried out again to obtain copper concen⁃
trate 2 and final sulfur concentrate product. The copper concentrate 1 and copper concentrate 2 are mixed in⁃
to a comprehensive copper concentrate product, and then the copper-molybdenum separation operation is
carried out to obtain the final copper concentrate and molybdenum concentrate products.
