| 中文摘要: |
| 以四川大岩子铂钯矿为研究对象，在岩矿鉴定的基础上，将白云岩、石英岩型铂族矿床中铂、钯和金的赋存状态划分为碳酸盐赋存相、硫化物赋存相、金属互化物相和残渣相。研究制定了各相态的浸取剂及浸取条件，并采用ICP-MS测定各相态中铂、钯和金的含量。结果表明，各元素各相态浸取量之和与样品各元素的总量之比分别为:铂94.3%~96.8%、钯99.9%~108%、金 91.0%~99.1%；矿物中铂、钯和金主要分布在硫化物赋存相、金属互化物相中。 |
| 英文摘要: |
| The occurrence states of gold, platinum and palladium in Sichuan Dayanzi platinum-palladium in pyrxenite are described. Based on the information of mineral identification, the occurrence states of gold, platinum and palladium in minerals of dolomite and quartzite type PGE deposits are divided into carbonate occurrence phase, sulphide occurrence phase, intermetallic compound(PGE alloy) and residue phase. After establishing the extraction agent and conditions, contents of gold, platinum and palladium in each phase were determine by ICP-MS. The results showed that, the ratios of the extracted aggregates amount sum of Pt, Pd and Au in each phase to their total contents of each element are 94.3%~96.8%, 99.9%~108% and 91.0%~99.1%, respectively. The sulfide state and PGE alloy state are the major states of platinum, palladium and gold in the occurrence. |
