金宝山铂钯矿多元素的相关关系与铂族矿物的产出形式

Multielemental Relationship of Jinbaoshan Pt-Pd Ore and Occurrence of Platinum Group Minerals

从元素的相关关系入手 ,对金宝山铂钯矿石的 Cu、Ni、Pt、Pd相关关系进行了研究。结果表明 :Pt、Pd与 Ni的相关关系远较 Cu密切 ,Pt— Fe密切相关性远大于 Pd— Fe,而 Pd— S的密切相关性远大于 Pt— S。在矿物组合方面 ,Pt主要以 Pt— Pd— Sn、Pt— Fe金属互化物形式产出 ,而 Pd绝大多数以与亲硫元素 Sb、As、Te、Bi化合物形式产出。 Pt、Pd矿物产于含

The relationship of Cu,Ni,Pt,Pd of Jinbaoshan Pt-Pd ore was investigated in this article.The research results indicated that the relationship between Pt,Pd and Ni is much more intimate than those of Pt,Pd and Cu,the relationship between Pt and Fe is much more intimate than those of Pd and Fe,and the Pd-S relationship is much more intimate than those of Pt-S,In the mineral association,the occurrence of Pt is principally in the form of Pt-Pd-Sn or Pt-Fe imtermetallic compounds,but the Pd is predominately in the form of compounds consisted of Pd and Sb,As,Te,Bi elements.The Pt,Pd minerals are occurred in Ni-containing minerals.
