辉钼矿

The process is advantageously conducted in conjunction with the roasting of molybdenite.

这个过程在有利进行的同时，辉钼矿也在焙烧。

The results showed that in the roasting process of the molybdenite, the manganese dioxide could not only have good function of sulfur fixation, but also lower roasting temperature obviously and promote the oxidation decompound of molybdenum disulfide.

结果表明，二氧化锰在辉钼矿焙烧过程中，不仅能起到良好的固硫作用，而且能显著降低焙烧温度，促进辉钼矿的氧化分解。

The results showed that the decompound ratio of molybdenum disulfide and ratio of sulfur fixation could reach 99.5% and 92% respectively when the reactant ratio n(MnO_2)/n(MoS_2) was 3, reaction temperature was 450℃ and 550℃, reaction time was all 2h, and air flow was 15-20ml/min. The calcine were leached by sulfuric acid when the temperature was 30℃, and the leaching ratio of molybdenum and manganese could reach 99% and 92% respectively.

结果表明，将辉钼矿(MoS_2)和二氧化锰(MnO_2)按摩尔比1：3的比例混合均匀，在管式炉中依次在温度为450℃和550℃下分别焙烧2小时，鼓风量为15-20ml/min，此条件下MoS_2的分解率可达99.5%以上，固硫率可以达92%。

Seven molybdenite samples from greisen ore body and quartz vein tungsten ore body associated with black tungsten ore were chosen for Re-Os isotopic dating and model age of (141.4±2.2) Ma~(158.2±2.2) Ma were obtained. The isochrone age of molybdenites from greisen type tungsten-tin ore body is (156.8±3.9) Ma, which indicates that its mineralogenetic epoch is at the Middle Jurassic, corresponds to the second stage of early Yanshanian period. And the model age for the samples from greisen ore body and from quartz vein ore body are (150.7±2.4) Ma~(158.2±2.2) Ma and (141.4±2.2) Ma~(151.0±2.4) Ma respectively, which indicates that the mineralization time of the quartz vein ore body is slightly earlier than that of greisen ore body.

文章选取云英岩型矿体及上部石英脉型钨矿体中与黑钨矿共生的辉钼矿7件，进行Re-Os等时线年龄测定，得到其模式年龄为(141.4±2.2) Ma~(158.2±2.2)Ma，其中云英型钨锡矿体中辉钼矿等时线年龄为(156.8±3.9)Ma，成矿时代为中侏罗世，对应于燕山早期第二阶段；从云英岩矿体中样品模式年龄为(150.7±2.4)Ma~(158.2±2.2)Ma，石英脉型矿体中样品模式年龄为(141.4±2.2)Ma~(151.0±2.4)Ma。

The massive sulphide, lead-zinc, iron, copper deposits of the former and the porphyry copper-molybdenum deposits of the latter are the main ore types in the region.3. The conclusions drawn through the research on the Re-Os isotopic geochronology of the Chilu Mo deposit are as follows:(1) the model age of the Chilu Mo ore deposit is 105.6Ma, closely to the 87Sr/86S isochrone age of the porphyric granite, adamellite. So they are closely correlated in the genesis, and both are the production of magmatic evolution of the late Yanshan.

Cu、Mo、Pb、Zn、Au为区内优势矿种。3、对赤路钼矿床的Re—Os同位素年代学研究得出如下结论：(1)赤路钼矿的矿化模式年龄为105.6Ma，与似斑状花岗岩、二长花岗岩等的87Sr/86Sr等时线年龄115±4Ma较接近，表明二者在成因上密切相关，同属燕山晚期岩浆演化的产物；(2)赤路钼矿床具有辉钼矿中Re、Os含量偏低，低87Sr/86Sr初始值和硫同位素组成接近陨石硫等特点，表明其为成矿物质来源于地壳深部，且为斑岩型钼矿床。

The process of roasting molybdenite mixed with manganese dioxide was a new process of chemical engineering and metallurgy of resources utilization and energy saving, and had good prospect of application.

因此辉钼矿和二氧化锰共同焙烧工艺是一种资源化、节能型的化工冶金新工艺，具有良好的应用前景。

The results showed that when the composite was filled with 25% nano-molybdenite,the electrical resistivity was 5.1×10~9 Ω·cm,the temperature for t_ to decompose increased by 35 ℃ and the diffraction peak of(002) in molybdenite shiftted by 1.12 degrees to the ...

This dissertation got the deposit forming of Qulong copper porphyry copper deposit by SHRIMP zircon U-Pb and Re-Os molybdenite methods.

对驱龙铜钼矿床进行了锆石SHRIMP U-Pb同位素定年及辉钼矿Re-Os同位素定年，获得新的年龄数据：含矿斑岩锆石SHRIMP U-Pb年龄为16.35～17.58Ma，矿石的辉钼矿Re-Os同位素年龄为15.36～16.85Ma。

Meanwhile the SHRIMP zircon U-Pb age of the fine-grained monzonitic granite is (131.4±1.6) Ma. These precise dating results represent the ore-forming period of this molybdenum deposit, the main dominant geological events and suggest its close relationship with buried Yanshan fine-grained monzonitic granite.

文章通过采集WZK1钻孔211.2~214 m细脉浸染状矿石的辉钼矿纯样，获得辉钼矿的等时线年龄为(134.1±3.3) Ma，并对比了矿区细粒二长花岗岩的锆石SHRIMP年龄(131.4±1.6) Ma，两者基本一致，表明矿床的形成主要与隐伏的燕山期细粒二长花岗岩有着密切关系。

Through the ReOs dating of molybdenite from quartz porphyry, the isochron age of (222.5±3.2) Ma and the model age of (222.1±3.2) Ma~(224.6±3.4) Ma were obtained, which means molybdenite formed in late Triassic.
