摘要
湖南东坡矿田铅锌矿床中的伴生银主要以独立银矿物形式存在,有银黝铜矿、黝锑银矿、碲银矿、硫银锡矿、深红银矿等;有少量的银以晶格银和超显微包体银矿物的形式赋存于方铅矿等矿石矿物中。文章还就银的富集规律作了初步探讨。
By using many analysis methods, the authors found out that the associated silver in Pb-Zn(Ag) deposits of the Dongpo orefield occurs mainly as independent minerals, such as freibergite, hes-site, cafieldite, pyrargyrite, ect. A part of the associated silver as isomorphism (lattice silver) and insupermicro-mineral form. The authors also summarize some enricthment rules of the associated silver.
