A benign alkaline process for scarce metal extraction and reagent recycle.

一种用于稀有金属提取和试剂回收的良性碱性工艺。该项目旨在在盐和非盐环境中选择性地从矿石中提取贱金属和贵金属，该项目建立在利用氧化和弱碱性溶液下的可食用甘氨酸的专利工艺基础上。从初级资源中提取金属的过程大多使用苛刻的、有毒的和/或不可回收的试剂。探索性研究已经表明，从碱性甘氨酸盐溶液中容易回收金属和回收浸出剂（甘氨酸）的潜力。预期成果是从初级资源中提取金属的安全、无毒工艺。

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.
