Base metals and gold are often found in association with magnetic minerals such as magnetite and pyrrhotite . 某些贱金属以及金常常与磁铁矿和磁黄铁矿这类磁性矿物一起被发现。

The disseminated blebs are generally composed of one pyrrhotite individual accompanied by varying amounts of pentandite and chalcopyrite . 分散的泡体常由磁黄铁矿个体与多少不等的镍黄铁矿及黄铜矿共生。

Reconnessance investigation of pyrrhotite in dongshan iron deposit of nanshan iron mine 南山铁矿东山矿床磁黄铁矿的普查研究
4.
The ore minerals are mainly composed of marmatlte , galenit , pyrrhotite ( pyrite ) , chalcopyrite , or marmatite , galenite , pyrite and hedenbergite . marmatite and hedenbergite are the indicated minerals of the ore 主要矿物组合为铁闪锌矿-方铅矿-磁黄铁矿(黄铁矿) -黄铜矿或铁闪锌矿-方铅矿-黄铁矿-钙铁辉石,其中铁闪锌矿和钙铁辉石为该类矿石标型矿物。

Pilsenite is a rare mineral and its information is deficient . the first found pilsenite in china is in gaozhuang , henan province . pilsenite , associated with pyrrhotite , pyrite , hessite , gold , produced in pyrrhotite - polymetallic stage . three bismuth - tellurides produced in gaozhuang are well concordant with the standard pilsenite in composition , and other three are different from any of known bismuth - tellurium minerals . single crystal diffraction were made on a larger mineral grain of pilsenite . au growth and decline together with bi and te in ores and wall - rocks , which suggests that bi and te play a important role in migration and enrichment of au 经电子探针分析,高庄金矿有多种铋碲化物,有三粒矿物的成分与标准叶碲铋矿完全一致。对一较大颗粒的叶碲铋矿做了单晶x射线衍射分析。 au与bi在矿石和围岩中的含量呈共消长关系, te与bi可能对au ag的迁移富集起了重要作用。
