方铅矿

Mineralization consists of galena, sphalerite, pyrite, and minor chalcopyrite, tetrahedrite and argentite in a gangue of mainly quartz and clay minerals.

矿化包含方铅矿、闪锌矿、黄铁矿、次生黄铜矿、及主要物质为石英和粘土矿物脉石内的黝铜矿和辉银矿。

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 main mineral composition of the ore is zinc blende and lead glance.

矿石矿物成份主要为闪锌矿，次为方铅矿。

The main ore minerals are chalopyrite、bornite、chalopyrite、pyrite and nature silver, are mineral zoned from redbed to graybed appear chalcocite、bornite、 chalcopyrite and pyrite, chalcocite occur in front of ore bodies.

矿石矿物主要为辉铜矿、斑铜矿、黄铜矿、黄铁矿和自然银，很少见闪锌矿和方铅矿。矿物分带明显，从红层、辉铜矿、斑铜矿、黄铜矿、黄铁矿到浅色层，辉铜矿形成于矿体的前锋。

The minerals are likely to be from the suite pyrite chalcopyrite, sphalerite, galena, fluorite and barite, and to be deposited at temperatures of between 50 and 250℃.

这些矿物可能由黄铁矿，黄铜矿，闪锌矿，方铅矿，萤石和重晶石组成，并且可能是在50～250℃之间的温度下沉积出来的。

Minor element discrimination indices for residual primary sulfides (pyrite, pyruhotite, chalcopyrite, sphalerite, galena, etc.) and supergene ore minerals goethite, hematite, manganiferons minerals, covellite, native gold, clay minerals, quartz, etc.

还给出了残余原生硫化物(黄铁矿、磁黄铁矿、黄铜矿、闪锌矿、方铅矿等)和表生矿物(针铁矿、赤铁矿、锰矿物、铜蓝、自然金、粘土矿物、石英等)的微量元素评价标志。

The effective potential range of self-induced flotation of galena and its lower and upper limits have been determined.

给出了方铅矿自诱导浮选电位区域和电位上下限，热力学计算表明了其意义。

G"1. when pH was in the range of 2.25-12.26, Kds of 125I" on chalcopyrite , galenite, pyrite and cinnabar decreased with increase of pH under atmosphere; but Kds of 125I on galenite increased with increase of pH under low oxygen ambience.

大气条件下，随溶液初始pH值的增大，125I-在黄铜矿、方铅矿上的Kd值均呈减小的趋势；而在低氧条件下，随溶液初始pH值的增大，125I-在方铅矿上的Kd值增大。

Its displayed 98% silver mineral of FengNing silver mine distributes in galenite and sphalerite and associate with galenite and sphalerite close., 1% silver mineral distributes in gangue.

研究表明：丰宁银矿的铅锌矿中银矿物有98%分布于方铅矿和闪锌矿中，并与方铅矿和闪锌矿紧密共生，有1%左右的银矿物分布于脉石矿物中。

Gelena is pretreated by sulphatization, forming a layer of PbSO_4 film on its surface. The film has no effect on arsenic minerals and gelena is depressed during reverse flotation.

通过硫酸化预处理，可使方铅矿表面形成一层PbSO_4覆盖膜，而砷矿物不受影响，从而在反浮选中，方铅矿受到抑制。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
