And some fabulous new samples of green Fluorite on Sphalerite and Galena from Naica, Mexico, which were collected some time this year - here Evan is holding one of the best examples of this new find.

还有一些新标本的如来自于墨西哥奈卡的闪锌矿和方铅矿上共生绿色萤石，这是今年的热门收藏，埃文在此次展会上最好的一批中淘到了一个。

Because of the lack of thermal expansion data of galena and sphalerite and to further examine the applicability of Modified Ruffa Model, galena and sphalerite,minerals with strong covalent characteristics, have been studied in detail.

论文还用修正Ruffa模型对前人没有进行过高温热膨胀实验的方铅矿、闪锌矿的热膨胀系数进行了预测和实验验证。实验所得到的热膨胀系数和计算结果具有较好的一致性。

Galenite and sphalerite is main carrier mineral and silver mineral is too small to reclaim solely.

方铅矿和闪锌矿是银的主要载体矿物，且银矿物粒度微细，难以单独回收。

Inductively coupled plasma atomic emission spectrometry was used to determine the main elements and trace elements in sphalerite.

利用电感耦合等离子体原子发射光谱法对闪锌矿中主元素与微量元素进行测定。

The δ〓S value of pyrite, sphelerite and arsonopyrite is in the range of 4. 0‰ and -4. 2‰ with the highest frequency occurring around zero, indicating a uniformed sulfur source. The large variation and mainly negative values (0.2‰～-11. 3‰) of δ〓S for stibnite could be interpreted by isotope fractionation. The carbon isotopic characteristics exhibit a mixing nature of magmatic carbon and organic carbon.

矿床中的热液成因黄铁矿、闪锌矿和毒砂的δ〓S＝4.0‰—-4.2‰，呈塔式分布，δ〓S集中在0附近，表明其成矿体系具有均—化硫的同位素组成，而辉锑矿的δ〓S变化范围较大(0.2‰—-11.3‰)，除一个样品外均为负值，这是硫同位素分馏作用的结果。

The new criterion of minimum principle of absolute harness for flotation reagents put forth The new criterion of minimum principle of absolute hardness for flotation reagents has been studied.

进行了银矿物的浮选研究天然的Ag〓S、Ag及合成的银浸染闪锌矿、AgCl、Ag〓SO〓、Ag〓O的单矿物浮选实验表明，这些矿物在pH≤5.5都具有很好的可浮性。

The selective adsorption of Nocardia on the surface of pyrite and sphalerite was studied under various conditions.

研究了诺卡氏菌在不同影响因素条件下，在黄铁矿和闪锌矿表面的选择性吸附。

Jamesonite, marmatite, pyrrhotite and pyrite are the complicated and mutiple-metal sulfide resources to process difficultly in Dachang Mine. Research on the basic theory of flotation electrochemistry and on potential-controlled flotation technology of the sulfide resources can be helpful to develop some new flotation theory and technology of the complicated and mutiple-metal sulfides, and to utilizate comprehensively the mineral resources, and to lower their production cost, and to improve the economical benefits. It is of important theoretical and practical significance.

脆硫锑铅矿、铁闪锌矿、磁黄铁矿、黄铁矿是大厂特有的难分离、难处理的复杂多金属硫化矿物资源，对其进行浮选电化学的基础理论和电位调控浮选技术研究，可发展复杂多金属硫化矿物浮选分离理论，形成复杂多金属硫化矿物浮选分离的创新技术，加强矿产资源的综合利用，降低成本，提高经济效益，具有重要理论意义和现实意义。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
