A benign alkaline process for scarce metal extraction and reagent recycle.. This project aims to selectively extract base and precious metals from their ores in saline and non-saline environments, building upon a patented process utilising edible glycine under oxidising and mildly alkaline solutions. Extraction processes of metals from primary resources mostly use harsh, toxic and/or non-recyclable reagents. Exploratory research has already indicated the potential for easy metal recovery from their alkaline glycinate solutions and recycling of the lixiviant (glycine). Anticipated outcomes are a safe, non-toxic process for extracting metals from primary resources.

用于稀有金属提取和试剂回收的良性碱性工艺。该项目旨在基于在氧化和弱碱性溶液下利用食用甘氨酸的专利工艺，从盐分和非盐分环境中的矿石中选择性地提取碱金属和贵金属。从初级资源中提取金属的过程大多使用刺激性、有毒和/或不可回收的试剂。探索性研究已经表明，可以从碱性甘氨酸盐溶液中轻松回收金属并回收浸滤剂（甘氨酸）。预期结果是一种从初级资源中提取金属的安全、无毒的过程。
