查询词典 iron pyrite

In this paper, the preparation of iron oxide yellow and iron oxide red with pyrite cinder was studied.

对利用硫铁矿烧渣制备氧化铁黄和氧化铁红进行了研究。

To that end, Wadia and his colleagues found that iron pyrite—better known as fool's gold—was several orders of magnitude better than any of the alternatives, based on both cost and abundance.

为了这一目的，瓦迪亚和他的同事们发现硫化铁---俗称傻瓜金，从储量及价格上优于其它任何替代材料几个数量级之多。

The organisms in the mine drainage, which lie in a pink slick on pools of acidic green water, obtain energy by oxidizing iron - that is, generating rust -- and in the process create sulfuric acid and dissole pyrite (iron sulfide or fool's gold) to release more iron and sulfur.

在铁矿排水的地方，这些微生物靠氧化铁离子来获得能量，在这过程中产生更多的硫酸融解黄铁矿，于是产生更多的离子和硫化物，造成水源污染，作者试验的地点中微生物造成了很大污染。

This subject is on the basis of a detail investigation of present utilization and recovery of pyrite cinder, and taking pyrite cinder from the Jinshandian vitriol factory of Wuhan Steel and Mining Industry Corporation as raw material. FeSO_4 is produced by adopting baking of pyrite cinder and vitriol lixiviation, and introducing the new high price ion during the course of making Poly ferric Sulphate to make Iron-modified flocculants.

本课题在对目前硫铁矿烧渣回收及利用现状进行深入综合考察的基础上，利用武钢矿业公司金山店铁矿硫酸厂的硫铁矿烧渣为原料，采用还原焙烧，酸浸工艺制取硫酸亚铁，在制取聚合硫酸铁的基础上引入新的高价离子，制取复合聚铁絮凝剂。

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。

Organic carbon-limited diagenetic pyrite added to the earlier formed syngenetic pyrite, which was controlled by the time that iron minerals remained in contact with H2S in anoxic waters.

其中以成岩黄铁矿为主，其形成过程主要受有机质限制，而同生黄铁矿受铁矿物与H2S接触时间的限制。

Finally, industrial policy for sulfuric acid industry in China is given: using reasonably both international and domestic sulfuric sources; developing vigorously and steadily the process of sulfuric acid production from sulfur; enhancing recovery and utilization of effluent gases from non-ferrous metal smeltery and combination sulfuric sources with non-ferrous metal mine; maintaining production capacity and output with iron pyrite as raw material; strengthening home-built work for large-scale sulfuric acid plant.

最后阐述我国硫酸工业的产业政策：合理利用国际，国内两种资源，积极稳妥地发展硫磺制酸；加强冶炼烟气制酸和有色金属伴生硫资源的回收和利用；稳定硫铁矿制酸能力和产量；加强大型硫酸装置国产化工作。

In this study, the feasibility of formation of iron phosphate coating on the pyrite surfaces and its role of the suppression of pyrite oxidation were carried out by utilizing kinetics and surface analysis techniques.

本文用动力学、表面分析技术方法研究在黄铁矿表面磷酸铁膜形成的可能性以及磷酸铁膜抑制黄铁矿的氧化作用。

The S entering into pellet with concentrate is pyrite, with coal powder are iron sulfide, sulphate and organic sulphur, when reducing, S existing in pyrite, iron sulfide and organic sulfur come into gas phase, then been absorbed by fresh Fe and liberate out of pellet, combined with CaO existing in outside of the pellet to form CaS finally, sulphate will remain in DRI.

当还原温度高于在铁碳相图中的最低液相线温度1147~1153℃时，渗碳作用导致DRI外壳熔化，这层致密的熔融外壳起到热态直接还原铁的防氧化作用。低于这个温度将有助于还原和脱硫。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
