Then in this disquisition by experiment of selectivity of pure Galenite and sphalerite, the rule is asscertained that the mine slurry pH and different adjust medicament and catch medicament and restrain medicament kinds and dosage affect flotation .

然后本研究通过对纯的方铅矿和闪锌矿物可选性的试验研究，确定了矿浆PH值、不同调整剂、抑制剂、捕收剂及活化剂的种类、混合配比和用量对浮选分离铅锌银矿石的影响规律，提出的适宜pH值范围、药剂种类及用量为实际矿石的铅锌分选和强化伴生银的回收奠定了良好的基础。

Data of major andminor elements in magnetite, cassiterite, galena and sphalerite from oredeposits within this ore belt suggest that these ore deposits are of skarn,hydrothermal, porphyry and greisen types related to Yanshanian magmaticactivity and that iron in ores came from regional Permian marine interme-diate-basic volcanic rocks whereas partial lead and zinc from Permian geo-synclinic sediments.

矿带中各矿床的磁铁矿、锡石、方铅矿、闪锌矿的主元素和微量元素数据表明，这些矿床是属与燕山期岩浆活动有关的矽卡岩型、热液型、斑岩型和云英岩型矿床；其成矿金属组分中的铁来源于区域晚古生代海相中-基性火山岩，部分铅锌来源于区域二叠纪地槽沉积物。

The isotopic ages,such as Pb-Pb model age of galena,Rb-Sr isochrone age of sphalerite and pyrite,indicate that there exist mineralization concentration in Jinding deposit at middle-late Trias(230Ma±),which must be the era of ore sources.

由方铅矿等矿石矿物的Pb-Pb模式法、闪锌矿和黄铁矿Rb-Sr法同位素定年结果显示，金顶矿床在中-晚三叠世(230Ma左右)时有一期矿化富集作用，可能代表了矿源的时代。

Metal minerals consist of major pyrrhotite, pentlandite, chacopyrite, violarite and pyrite, with minor millerite, niccolite, magnetite, ilmenite and galena.

矿体的形态产状：似层状矿体、似板状矿体、脉状矿体、纯硫化物脉状矿体、上悬透镜状矿体、主要金属矿物有磁黄铁矿、镍黄铁矿、黄铜矿、紫硫镍矿、黄铁矿；次要矿物：针镍矿、红砷镍矿、磁铁矿、钛铁矿、方铅矿等。

In this deposit, ore bodies exist in the stratoid form and are c ontrolled by thrust faults. The host rocks are limestone in Bolila Formation of Late Triassic Jiezha Group and in Gadikao Formation of Early-Middle Permian Kaix i nling Group, with strong dolomitization and weak silicification. Minerals are ra ther simple and consist of sphalerite, galena, pyrite, calcite, dolomite and barite. The important ore textures are colloforms such as framboid and crust and xenom orphic grains, and the ore structures are in disseminated, brecciated, veinlike and lumpy forms.

东莫扎抓铅锌矿床矿体呈似层状展布，产状严格受到矿区逆冲断层的控制，赋矿围岩为上三叠统结扎群波里拉组灰岩和下-中二叠统开心岭群尕迪考组灰岩，发育强白云石化和弱硅化，矿物组合简单，主要为闪锌矿+方铅矿+黄铁矿+白云石+方解石+重晶石，矿石结构以皮壳状、草莓状等胶状结构和他形粒状结构为主，矿石构造为浸染状、角砾状、团块状和脉状。

Independent silver minerals in the deposits areargentite, native silver, polybasite and freibergite, which are mainlydistributed within galena.

矿床中显微级独立银矿物有辉银矿、自然银、硫锑铜银矿和银黝铜矿，主要分布于方铅矿中。

Silver has two forms in its occurrence:mainly in the form of silver-bear iug sulfosalts(pyrargyrite,freibergite and Ag,Zn-bearing tetrahedrite and others) discovered for the first time;secondary,in the form of impurities scattered in the memllic sulfides.

银主要以首次发现的含银硫盐矿物（深红银矿、银黝铜矿和含银锌黝铜矿等）产出，其次是杂质元素分散在金属硫化物中，银的含量按方铅矿、黄铜矿、闪锌矿、黄铁矿的顺序依次降低。

The metallic minerals in the ore occur as sulfides. Galena and sphalerite coexist with pyrite and barite.

矿石中金属矿物以硫化物形式存在，方铅矿、闪锌矿与黄铁矿、重晶石等共生。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
