河南省某银矿床的银主要是独立矿物——自然银和辉银矿,此外,在金属硫化物中(方铅矿、黄铁矿、闪锌矿等)也赋存着较多的银。但对后者的赋存状态并未探明。本文通过化学分析,研究了方铅矿中银的各种状态及含量,确定了它们的分配率,并根据相关分析、多点微量分析、X射线衍射分析等结果,论证了方铅矿中银的赋存状态。 Silver in a silver deposit in Henan Province is mainly independent minerals - natural silver and silver mine, in addition, the metal sulfide (galena, pyrite, sphalerite, etc.) also exist more silver. However, the state of existence of the latter is not proven. In this paper, through chemical analysis, various states and contents of silver in galena were studied and their distribution rates were determined. According to the results of correlation analysis, multi-point trace analysis and X-ray diffraction analysis, Save the state.
