铁矿

The scientists found green-yellow trace on a stone urinated by some deer . Follow this clue, he found ironmine.……

科学家们在树林里发现小鹿洒的尿打在石头上有青黄色的痕迹，于是发现这下面原来有大量的铁矿……

Shanxi was an important province of north China which largely produced iron in Song, Yuan, Ming, Qing dynasty. There were a lot of places to exploit iron ore, and exploitation scale was increasing. The technique of smelting iron was generally improved and pig iron outputs increased. All kinds of handworked ironworks not only satisfied the production and living requirement of this province, but also were sold to other provinces, even abroad. Smelting iron industry became an important handicraft industry of this province, which directly promoted the economical development of Shanxi.

宋元明清时期，山西是北方重要的产铁大省，铁矿开采点多，开采规模扩大，冶铁技术得到普遍提高，生铁产量增加，各种手工铁制品不仅满足本省生产生活需求，而且远销其它省份甚至国外，铁冶业成为本省重要的手工业部门，直接推动着山西经济的发展。

The quality of these small mines are poorly managed and the economic benefits for the plan, and some in the ore-doped large number of non-ferrous metal debris, some with low-grade ore exports of high-grade pretending.

而这些小矿山质量管理落后，为图经济利益，有的在矿石中掺杂大量的非铁矿杂物，有的以低品位矿石冒充高品位出口。

High-grade iron ore is mined at nearby Lugu.

高档铁矿开采，附近是绿谷。

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。

During the sintering process, the calcium carbonate reacts with iron ore to from the calcium ferrite as a bonding matrix. The productivity and strength of sinter phase are mainly controlled by the volume and texture of calcium ferrite.

炼钢过程中所用之助熔剂包括了碳酸钙系列与氧化镁系列等矿物，其中以碳酸钙会与铁矿在烧结制程中形成铁酸钙为主的成分，且其化学成分与烧结相的存在会影响烧结矿之产率与强度。

This article analyses the management problems in Jianping county's iron mineral industry unifying the concrete characteristics of Jianping's iron management,and proposes sustainable development strategies like the attraction of investments, the network marketing as well as the establishment of modern enterprise system.

本文通过对建平县铁矿业经营管理中问题的分析，结合建平县铁矿经营的具体特点，提出了招商引资、网络营销以及建立现代企业制度等可持续发展战略。

There are some microtubular and spiral goethites scattered among the iron hydroxide colloidal cloud and submicrometer-size colloidal particles.

电子显微分析观察到在非晶质氢氧化铁凝胶团和亚微米级微粒聚集体中存在特殊的显微管状和螺旋状针铁矿，显示出明显的生物矿化特征。

IR, XRD, SEM and TEM analyses show that crystalline minerals in the iron hydroxide sediments are mainly weakly-crystallized goethite with small amounts of illite and montmorillonite.

析出物的主要成分为Fe2O3，并含少量Al2O3和SiO2，铁质析出物的XRD、IR、SEM和TEM分析表明，氢氧化铁的结晶程度较低，主要结晶相为针铁矿，其次为少量伊利石、蒙脱石和石英。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
