砷

Depending on the characteristics of the low grade oxidized ore on the surface in Woxi,and by small scaled column leaching tests and commercially scaled heap leaching tests,a flowsheet of heap leaching-carbon adsorption-disadsorption and electrowinning was applied,where masking agent was used to reduce the influence of Arsenic and antimonial on cyanidation.

According to the Vegard's law and density functional theory of quantum mechanics, the lattice match conditions of Boron-contained arsenide and antimonide quaternary materials have been deduced, the bandgap properties of such quaternary materials have been theoretically analyzed, and the bandgap bowing parameters of all ternary compounds included have been theoretically calculated.

依据维加德定理和量子力学中的密度泛函理论计算出含硼砷化合物和含硼锑化合物四元系材料与GaAs、Si晶格匹配的条件及其带隙性质，同时计算出上述四元系材料所含三元系材料的能带弯曲参数，进而推导出BInGaAs、BInAlAs、BGaAsSb和BGaPSb四元系材料的发光波长与硼元素并入比例的关系。

In the north limb, however, the PGE mineralization developing in contact zone is referred to Platreef. The mineralization is discontinuous, and the characteristics of different deposits vary along the trend with the changes in footwall lithology. The PGE carriers are dominantly semimetal compounds such as arsenide, telluride and antimonide.

PR接触带型矿化集中在杂岩体北段，整体上不连续，各个矿床的具体特征由于底盘岩性的多变而不同，PGE主要赋存在碲化物和砷化物等半金属化合物中，可以脱离硫化物产在硅酸盐矿物中。

There develops a typical epithermal mineral association in the deposit, which consists of zinckenite, diaphorite, antimonite, tennantite, native gold, pyrite, sphalerite, orpiment, realgar, and mercury oxide.
