云南会泽铅锌矿床分散元素镉锗镓的富集规律

Enrichment of the dispersed elements Cd,Ge and Ga in the Huize lead-zinc deposit,Yunnan

摘要: 本文利用电子探针和等离子质谱分析手段,对会泽铅锌矿床矿物和矿石的分散元素镉锗镓进行了分析研究,认为矿床中分散元素镉、锗、镓的赋存状态以类质同象形式存在。矿床以富集镉、锗为特征,其中镉主要富集于闪锌矿之中,锗和镓主要富集于方铅矿之中。

Abstract: The approaches to the enrichment of the dispersed elements Cd,Ge and Ga in the minerals and ores from the Huize lead-zinc deposit,Yunnan have been made by means of electron microprobe and ICP-MS.The authors contend that the studied dispersed elements occur in the form of isomorphism.The element Cd is enriched in sphalerite,and the elements Ge and Ga abound in galena from the Huize lead-zinc deposit.
