摘　　要：曹四夭超大型钼矿床赋矿围岩为中太古界中深变质结晶岩系,主要矿石类型为细脉浸染状。除主要有用矿物辉钼矿外,尚含少量黄铁矿、黄铜矿及磁黄铁矿。总体选矿方案为浮选,通过一段、二段探索性试验、细度条件实验、开路实验及闭路实验,使Mo的回收率达到93.02%,最终钼精矿的品位达45.48%,达到行业标准二级品二类要求,充分证明该矿床矿石为易选。The wall rock of Caosiyao super large molybdenum deposit belongs to the deep metamorpmc crystal series, mid -Archean Erathem. Rock types of which are mainly disseminated fine vein. In addition to the main useful mineral molybdenite, it also contains a little pyrite, chalcopyrite and magnetic pyrite. The general processing scheme is flotation, Mo recovery ratio can reach 93.02% after two steps of exploratory experiment; fineness condition experiment, open and closed circuit experiment, and then the final molybdenum concentrate grade could reach 45.48%, which can be up to the second category of industry standard, this fully proves that the ore of the deposit is easy to be concentrated.
