9404622 Wood This project is to do the following: 1) carry out studies of the hydroxide and bisulfide complexes of Pt and Pd from 0 to 90oC; 2) build and test a hydrothermal apparatus required for the study of PGE mineral solubility at temperatures from 300o to 600oC; 3) carry out preliminary experiments on the simultaneous solubility of all six PGE metals in chloride solutions from 300o to 600oC. The thermodynamic data determined in this study are crucial to the direct modelling of PGE transport during the formation of low-temperature hydrothermal PGE deposits.

9404622木材本项目主要做以下工作：1)在0 ~ 90℃范围内进行Pt和Pd的氢氧化物和二硫化物配合物研究；2)建立并测试在300 ~ 600℃温度下研究PGE矿物溶解度所需的水热装置；3)对6种PGE金属在300o ~ 600oC氯化物溶液中的同时溶解度进行初步实验。本研究确定的热力学数据对于低温热液PGE矿床形成过程中PGE输运的直接建模至关重要。
