硫化物

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。

The raw data and certified data for gold in gold-bearing minerals including free gold F(subscript Au, linked gold L(subscript Au, gold-bearing sulfides S(subscript Au, another gold-bearing minerals A(subscript Au and total-gold T(subscript Au were presented.

介绍了金矿石化学物相分析标准物质的研究工艺及技术关键，列出了单体金、连生体金、硫化物包裹金、其他矿物包裹金及总金的原始数据和定值数据。

The massive sulfide contains fragments of barren and mineralized gabbro, and schist

块状硫化物中含有矿化的和未矿化的辉长岩及片岩碎块。

The massive sulfide contains fragments of barren and m ralized gabbro, and schist.

块状 硫化物中含有矿化的和未矿化的辉长岩及片岩碎块。

The mineral galena is composed of lead sulfide.

方铅矿这种矿物就是由铅硫化物组成的。

Lead is rarely found free in nature; its major ore is the sulfide galena.

铅在自然界中很少呈游离态，主要存在硫化物和方铅矿中。

It can draw the conclusion thatδ~(34)S_ in solution has an approximate content(0±3‰)with S isotope of pyrrhoSne by measuring S and Pb isotope of sulfide in ore bodies,a lower value shows S in hydrothermal fluid is origin from magma;Linear array of Pb isotope in galenite suggests that Pb may be multisources.

对矿体硫化物进行硫和铅同位素测定，获得溶液的δ~(34)S_与磁黄铁矿硫同位素组成相近约等于0±3‰，δ~(34)S_值小，表明热液硫是岩浆来源，方铅矿铅同位素线性排列，暗示出铅可能是多来源的。

According to craft mineralogical research result, use raw ore to wait for sulfide via floatation eliminate realgar, gamboge first, soak of the cyaniding after floatation concentrate pretreatment, the plan of direct cyaniding soak undertakes floatation gangue experiment, total soak rate of gold is achieved 88.52%, relatively raw ore is direct soak of complete mud cyaniding increases 25.02 percent.

根据工艺矿物学探究结果，采用原矿先经浮选除去雄黄、雌黄等硫化物，浮选精矿预处理后氰化浸出，浮选尾矿直接氰化浸出的方案进行试验，金的总浸出率达到88.52%，较原矿直接全泥氰化浸出提高25.02个百分点。

The gasolene, kerosene, and the gas oil fractions are purified to remove unwanted materials, mainly sulphur compounds.

汽油，煤油，和气体油馏分被提纯以去除不想要的物质，主要是硫化物。

Hongqiling Cu, Ni sulphide deposit is located in ca. 45km south of Panshi city, Jilin province. It is also situated tectonically in the Tieling contact zone between Jihei geosyncline and Liaodong syncline in North China plate, which is divided by Huifahe fault.

红旗岭铜镍硫化物矿区位于吉林省磐石市南约45Km，地处吉黑地槽与华北台块辽东台背斜铁岭台凸接触地带，辉发河断裂是其分界线，特殊的构造位置决定了本区的构造活动强烈，岩浆活动发育，具备良好的成矿环境和条件。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
