闪锌矿

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。

Based on a systematic study of a considerable number of polished ore sections as well as ICP-MS and electron microprobe analyses, the authors have found that the main sulfide minerals include galena, iron-poor sphalerite and chalcopyrite, whereas silver minerals are composed chiefly of native silver, pyrargyrite, argentite, polybasite, and argentiferous freibergite.

文章首次对其矿石矿物进行了系统的研究，通过对大量矿石光薄片观察、等离子质谱和电子探针分析，表明具有工业意义的硫化物主要有方铅矿、贫铁闪锌矿、黄铜矿，银矿物主要有自然银、深红银矿、辉银矿、硫锑铜银矿、含银黝铜矿，它们与硫化物共生，多沿方铅矿、贫铁闪锌矿等颗粒间或者裂隙产出。

The results show that the CdSe nanorod with zinc blende structure is formed at 200℃ reaction temperature.

结果显示反应温度为240℃生成纤锌矿型CdSe纳米棒，反应温度为200℃生成闪锌矿型CdSe纳米棒。

The three structures characterized by the inter-potential are wurtzite structure,zinc blende structure,and Rocksalt structure.

利用该作用势得出了六配位数碱卤化物晶体的性质，并描述了CdSe的三种晶体结构：纤锌矿、闪锌矿和岩盐矿型结构。

On the base of theorial study,ore experiment is made and feasible grind granularity and medicament system and the flow of Galenite flotation firstly is ascertained.

在优先选铅浮选过程中，经一次粗选，一次扫选，两次精选，所得到铅精矿中铅的品位达66.04%，铅的回收率为87.31%，银的回收率为70.40%，在浮选锌时，一次粗选，两次扫选，两次精选，所得锌精矿中锌的品位58.26%，锌的回收率为82.13%，银的回收率为19.36%，取得了银的总回收率达89.76%较先进的指标。最后，对浮选药剂与方铅矿、闪锌矿和银矿物的作用机理进行了深入探讨与分析，认为本实验中所使用的抑制剂和活化剂不会对银矿物的回收产生不利影响。

Marmatite was much easier to be oxidized through electrochemistry than sphalerite.

与闪锌矿相比，铁闪锌矿更易发生电化学氧化。

No cadmium ore is mined for the metal, because more than enough is produced as a byproduct of the smelting of zinc from its ore, sphalerite, in which CdS is a significant impurity, making up as much as 3%.

没有为了开采镉而开矿的，因为从锌矿中提炼锌的时候产出的副产品已经是绰绰有余了，在闪锌矿中镉是最主要的混杂物，大概占3％。

The simulation of Fe doped sphalerite (110) surface and Cu adsorption on the sphalerite surface were performed by using plane wave-pseudopotential approach based on density-functional theory.

摘 要：采用基于密度泛函理论的平面波赝势法对含铁杂质闪锌矿(110)表面电子结构及铜在闪锌矿表面的吸附进行模拟。

The results show that jamesonite and pyrrhotite have good floatability in the pH range of 2-10 and marmatite has good floatability in the acid and it is difficult to separate these minerals. In the pH range of 6-8, the separation of jamesonite and pyrrhotite, marmatite is possible when using mercaptoacetic acid and mercaptoethanol as depressants. In case of the presence of Cu2+ ion, however, it is difficult to separate the three minerals. Infrared spectrum demonstrates that there are a number of function groups such as —SH,—COOH,—OH in the molecular structure of depressant.

结果表明：用丁黄药作捕收剂，脆硫锑铅矿和磁黄铁矿在pH 2~10范围内都有良好的可浮性，铁闪锌矿在酸性条件下可浮性好，三者分离困难；在pH 6~8之间，采用巯基乙酸和巯基乙醇作抑制剂，脆硫锑铅矿与磁黄铁矿和铁闪锌矿的分离是可能的；但铜离子存在时， 3种矿物之间的选择性分离是难以实现的。

The results show that the maximum growth quantity of Nocardia can be achieved after culturing 120 h and obvious selective adsorption of Nocardia on the surface of pyrite and sphalerite can be detected. The maximum adsorption rate on the surface of pyrite is 96.99%, whereas it is less than 20% in the case of sphalerite. Adsorption equilibrium can be attained within 20 min on the surfaces of the two minerals. pH value is the key factor influencing upon selective adsorption, and the difference of adsorption quantity on the surfaces of two minerals is apparent when pH is between 4 and 10. Slurry concentration over 6 g/L is favorable to selective adsorption. Nocardia cell concentration, stirring speed and temperature have no obviously effect on selective adsorption.

结果表明：培养120 h后诺卡氏菌达到最大生长量；诺卡氏菌在黄铁矿和闪锌矿表面发生明显的选择性吸附，在黄铁矿表面的最大吸附率可达到96.99％，而在闪锌矿表面的吸附率大都在20％以下；诺卡氏菌在两种矿物表面于20 min内即可达到吸附平衡； pH值是影响诺卡氏菌在两种矿物表面发生选择性吸附的关键因素， pH在4～10之间时，选择性吸附现象明显；矿浆浓度超过6 g/L时有利于发生选择性吸附；细胞悬浊液浓度、搅拌速度和温度对吸附效果影响不大，均可产生选择性吸附。
