| 摘 要： | 本文在矿物结晶化学理论分析的基础上,借助于Auger电子能谱测试结果,研究了毒砂与黄铁矿颗粒的表面化学组成,以确定毒砂与黄铁矿的表面特征,寻求它们之间分离困难的根本原因。首次提出毒砂颗粒存在两种表面,即FeS]和AsS]。其中FeS]和黄铁矿表面FeS_2]类似。这一结果是分析一切有关毒砂表面现象的基础。

| Abstract: | On the basis of theoretical analysis of mineral crystalline chemistry, surface chemical compositions of arsenopyrite and pyrite particles were studied with Auger microprobe, in order that surface characteristics of arsenopyrite and pyrite can be determined to explore the main reason of the difficult separation of these two minerals, It is suggested at first time that there exist two kinds of surfaces on crushed arsenopyite particles, That is, FeS] and AsS]consist of surface phase of arsenopyrite particles, of which FeS] is very similar to pyrite surface FeS_2]. This result is the basis of analyzing all surface chemical phenomena of arsenopyrite. |
