黄铁矿

Today, I'll give you a pyrite and an agate and wish you would like them.

我送你的是一个黄铁矿和一块小玛瑙，希望你喜欢。

They crystallized in veins that are several centimeters in diameter, which were made up mainly of calcite, sodium feldspar albite, and iron sulfite pyrite.

它们体现在那些静脉直径几厘米，其中大部分为方解石，钠长石钠长石，黄铁矿和铁的亚硫酸盐。

For example, the secondary overgrowth quartz, authigenic illite, and authigenic ankerite on the cementation was inhibited by oil emplacement, but pyrite was mainly distributed in oil layer and oil water layer, particularly rich in oil water layer.

由于烃类的侵位，使石英的次生加大、自生铁白云石的生长受到抑制，同时也对自生伊利石生长有抑制作用，黄铁矿由于烃类侵位分布在油层、油水层，尤其在油水层中较为发育。

The results showed that the trace elements were not anomalously enriched. Zn and Cu existed in sphalerite. Cr, Pb and Cd were adsorbed by clay minerals. Ba might exist in ankerite and calcite. Ni, Mo, Co and As mainly existed in pyrite. Be and Se were combined with organics. Many trace elements were difficult to volatilize. Because of high content and volatility, Pb and Zn, are harmful to environments; Zn and Pb separately exist in sphalerite and clay minerals, so it is easy to reduce their environmental damage by washing and processing of coal.

结果表明：研究的元素没有异常富集；Zn和Cu赋存于闪锌矿中，Cr、Pb和Cd被粘土矿物吸附，Ba可能赋存于铁白云石和方解石中，Ni、Mo、Co和As主要赋存于黄铁矿中，Be和Se以有机结合态存在；研究的元素大多不易挥发，但Zn和Pb易挥发，且含量较高，环境危害较大，Zn和Pb分别赋存于闪锌矿和粘土矿物中，可通过洗选脱除减小其危害。

High salinity fluid inclusionscontaining daughter minerals have been found in quartz and ankerite of main mineralizingstages, Taibai and Baguamiao gold deposits of Shaanxi province, located in South Qinling.Both deposits occur in Devonian low-grade metamorphic rocks. Daughter minerals weredetected as pyrite, ankerite, halite and arsenopyrite by SEM/EDS and EPMA.

对赋存于南秦岭泥盆系浅变质碎屑岩中的陕西太白金矿、凤县八卦庙金矿主成矿阶段的石英和含铁白云石中的流体包裹体进行研究，发现局部富含高盐度、含子矿物的流体包裹体，通过光学显微镜、电子探针、扫描电镜/能谱发现子矿物主要为黄铁矿、铁白云石、石盐、毒砂及一些成分复杂的子矿物。

The sulphur in E'Kou Ironstone comes from sulphide (pyrite,pyrrhotite,chalcopyrite, binarite)and sporadically distributes in the ore or veined parallels/intercalates banded ferrosilicon formations.

峨口铁矿矿石中的硫来源于硫化物(黄铁矿、磁黄铁矿、黄铜矿、白铁矿)，呈星点状，散布于矿石中或呈脉体平行或穿切硅铁建造条带。

At pH=11-13, N-pyrite and sp halerite are the best adsorbent of nanometer-sized gold, with the adsorption co efficients being as high as 100%, 83% and 63%.

11.7％。在pH＝11-13的条件下，N型黄铁矿和闪锌矿对纳米金的吸附作用最强，吸附率为100％，黄铜矿为83％，P型黄铁矿为63％。

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。

High temperature is favorable to the formation of low valence state-As minerals and to the addition of As into pyrite crystal lattice, thus is favorable for the formation of P type of pyrite. However, at low temperature, high valence As minerals are easily formed and this case is not suitable for As to add into the pyrite crystal lattice to substitute S, thus the low temperature is beneficial to the formation of N type of pyrite.

As在白然界中的赋存状态与温度的关系表明：高温有利于形成低价态的As矿物，也有利于As呈低价态进入黄铁矿晶格中替代S而形成P型导电；低温则有利于形成高价态As的独立矿物，不利于As呈低价态进入黄铁矿晶格中替代S。，因而有利于形成N型导电。

The results indicated that the metal values Mn、Cu、Ni、Co contained in nodules could be extracted effectively in dilute chloric acid solution with the addition of pyrite as reductant, which exists widely in the nature.

结果证实稀盐酸中采用自然界广泛存在的黄铁矿作还原剂可以有效地浸取锰结核中的有价金属Mn、Cu、Ni、Co，黄铁矿中的硫最终将氧化生成硫酸根。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
