查询词典 pyrite

The effects, such as the acidity of leaching system, the temperature and the concentration of the sodium chloride, on oxidation and leaching of copper-bearing gold ores were analyzed. The results show that the sequence of sulfide ores oxidized and dissolved are pyrrhotite firstly, sulphide secondly, then chalcopyrite, pyrite lastly.

结果表明：硫化矿的氧化溶解首先是磁黄铁矿，其次是铜的次生硫化矿，再次是黄铜矿，最后是黄铁矿；载金黄铜矿的氧化首先是铁从黄铜矿的晶格中氧化溶解出来，生成中间产物CuS2和CuS；较高的酸度和氯化钠浓度有利于单质硫的生成、三价铁的水解和铜的浸出，进而有利于金浸出率的提高。

Exotic goods found their way to Waka as well. Jade for sculpture and jewelry and quetzal feathers for costumes came from the mountains to the south, and obsidian for weapons and pyrite for mirrors from the Mexican plateau to the west, the domain of Teotihuacan.

外来物品也出现在瓦卡，雕刻、制作珠宝用的玉和用来缝制服饰的凤尾绿咬鹃羽毛都来自南方山区；制作武器用的黑曜岩和制作镜子用的黄铁矿，则来自西边属于特奥蒂瓦坎领域的墨西哥高原。

In light of production practice, the author introduces some measures for reducing copper content of electric furnace slag to .8%: aplication of new type of concentrate nozzles, stabilization of flash furnace slurry, addition of coke powder to flash furnaces, control of the Fe/Si ratio of furnace slag, increasing the time for clarification of copper liquor, and addition of reductants, such as coal or pyrite.

结合生产实践，介绍了控制电炉渣含铜低于 0 。8%的几点措施：采用新型精矿喷嘴，稳定闪速炉炉浆；向闪速炉中添加焦粉；控制炉渣的铁硅比；增加铜液澄清时间；向电炉中加入还原剂煤块或黄铁矿等。

Lively text, accurate maps, and clear route descriptions enable you to find rhodonite, agate, pyrite, quartz, and much more.

生动的文字，准确的地图，和明确的路线描述可以使你了解辉石，玛瑙，黄铁矿，石英，等等。

In ore deposits on tops of the paleokarst denudationplanes,sericite is the most important carrier of gold.whereas in the ore depo-sits within the faults,pyrite is the most important carrier of gold.

不同的"卡林型"金矿床之间，由于形成的物理化学条件的差异，其主要载金矿物的种类也不相同。

The early mineralization is related to sedimentation, which resulted in the formation of the siderite ore-body and some pyrite orebodies.

作者在综合分析该矿田的地质－地球化学特征的基础上，认为新桥矿田具有二期成矿作用的特点早期沉积成矿作用形成菱铁矿矿体和不具有工业意义的黄铁矿层。

The enrichment of minerals such as siderite and pyrite, which are sensitive to geochemical environment, in the transitional zone indicates that the geochemical environment is neutral-acidic and reductive and is propitious to the precipitation of uranium.

过渡带中菱铁矿(FeCO3)和黄铁矿(FeS2)等对地球化学环境敏感的矿物的富集，指示了有利于铀成矿的中性-弱酸性、还原的地球化学环境。

Iron oxides would continue to be formed or at least not to be dissolved under oxic conditions, and the sediments in brown to red color will then be dominant. While in a reducing environment, iron oxides will be dissolved, with the possible migration of iron ion in the ocean, and then buried as siderite, pyrite, or other ironbearing minerals.

氧化强氧化条件利于沉积物中氧化铁的持续产生或者至少保持不被溶解的状态，从而形成棕色-红色沉积物；还原条件利于沉积物中铁氧化物的溶解，形成菱铁矿、黄铁矿等形式的埋藏，并可能造成溶解铁在海洋内的迁移。

It was found that, in comparison with O2/N2 combustion, O2/CO2 combustion does not affect the iron-bearing phases formed, however, it does affect their relative amounts in the ashes. O2/CO2 combustion favors the included pyrite and siderite to form iron-containing glass silicates rather than oxidizing to form iron oxides.

结果表明，与O2/N2燃烧相比，O2/CO2燃烧对灰中生成的主要含铁矿物相种类没有影响，但显著地改变了灰中含铁矿物相的相对含量；O2/CO2燃烧更有利于内在黄铁矿和菱铁矿生成硅酸盐玻璃体而不是氧化成铁氧化物。

Arsenian pyrite is the most important Au-bearing mineral, and silicification with quartz veins is the well-marked hydrothermal alteration.

含砷黄铁矿是该矿床最主要的载金矿物，硅化及石英脉是最显著的热液蚀变类型。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
