毒砂

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。

This is attributed to the formation of paramagnetic center resulting from the substitution of Au~+ ion and etc.

这是由于在含金黄铁矿和含金毒砂中，Au~+等不同电价的离子替换晶格中的Fe~(2+)，产生顺磁中心。

The main alterations related to gold mineralization are pyritization、silicification and carbonatization.

与金矿化有关的蚀变类型主要有黄铁矿、毒砂化、硅化、碳酸岩化和粘土岩化等。

Experimental results indicate that the growth of bacteria is retarted seriously in the media containing ethyl xanthate more than

对矿石抛光面实验的结果表明，细菌对黄铁矿的浸蚀作用在晶格缺陷处和解理面方向均可进行；而对毒砂的浸蚀作用则只在缺陷较为明显处选择性进行，显示出细菌对黄铁矿的直接作用更为明显。

According to analysis to poisonous grit mineral character,discussion about how to conquer arsenic in vulcanization ore and the investigations of much cassiterite metal vulcanization ore , much cassiterite metal vulcanization ore is a new kind of reagent,it is effective in reducing arsenic.

通过对毒砂矿物性质的分析，探讨硫化矿降砷及锡石多金属硫化矿选别试验，得出锡石多金属硫化矿浮选降砷的有效抑制剂为TS-1新药剂。

Six kinds of minerals, such as pyrites, arsenopyrite, sphalerite, galena and cassiterite from various metallogenic stages, ore blocks and ore type s were analyzed by EMPA.

文章总结和划分了矿床的矿石类型、矿化阶段及其在空间上的分布；对不同阶段、不同地段和不同类型的黄铁矿类、毒砂、黄铜矿、闪锌矿、方铅矿和锡石等 6种主要矿石矿物进行了电子探针微区分析。

The mineral mode of Cassiterite, Jamesonite, Marmatite, Arsenopyrite, Pyrite and Magnetic Pyrites are established on the basis of the the grade model of No.100 ore-body. The maps of sections and planes are plotted and the mineral deposit is calculated.

在矿床品位建模的基础上建立了锡石、脆硫铅锑矿、铁闪锌矿、毒砂、黄铁矿和磁黄铁矿等六种矿物的矿物模型，并编制了各种图件和进行了矿物量的计算。

The Yiarmand gold deposit occurs in hydrothermally eruptive breccia of the 2nd Member of Lower Carboniferous Dahalajunshan Formation and its underlying arsenopyritized and pyritized tuffaceous clastic rocks,and the ore forming process can be divided into hydrothermally eruptive and sedimentary stage and metasomatic stage.

伊尔曼德金矿床赋存于下石炭统大哈拉军山组第二岩性段硅化热液喷发角砾岩及其下伏上泥盆统吐呼拉苏组毒砂黄铁矿化凝灰质碎屑岩中，成矿作用可分为热液喷发沉积期和热液交代蚀变成矿期。

So the original gold ore in XIAOSHIREN can not be cyanized directly.

晶格中金，在黄铁矿、毒砂、赤铁矿等矿特的晶格面网中赋存有几个埃至几十埃的金矿物。

It is also found that Au content varies substantially in different crystal striations, therefore it is proposed that Au came into the crystal structure of the arsenopyrites when they formed.

此外，金含量在不同的生长环带中有显著变化，表明Au是在毒砂形成过程中进入其晶格的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
