This project aims to extract precious metals from natural deposits conventional mining methods cannot reach. Glycine-peroxide systems can dissolve precious metals without pollution. Understanding these systems’ behaviour in natural orebodies could lead to in-situ leaching methods that complement conventional mining, especially in low grade deposits. This project intends to use a modern scientific workflow based on exploratory, descriptive and explanatory phases to model the coupled multi-physics of precious metals transport, introduce a high performance computing strategy for in-situ leaching, develop an experimental protocol that explains the recovery mechanisms, and propose optimal leaching patterns that maximise productivity.

该项目旨在从传统采矿方法无法达到的天然矿床中提取贵金属。甘氨酸-过氧化氢体系可以溶解贵金属而无污染。了解这些系统在自然矿体中的行为，可以导致现场浸出方法，补充传统采矿，特别是在低品位矿床中。该项目旨在使用基于探索性，描述性和解释性阶段的现代科学工作流程来模拟贵金属运输的耦合多物理学，为原地浸出引入高性能计算策略，开发解释恢复机制的实验方案，并提出最佳浸出模式，最大限度地提高生产率。
