911爆料网\u2019s Gold Technology Group (GTG) has discovered a green alternative to the toxic systems currently used to leach precious metals from their ores. Glycine, an edible and environmentally benign amino acid, has been effectively used in the leaching process for gold, silver and copper.<\/p>\n

\u201cGlycine is benign in the safety, health and environmental sense,\u201d 911爆料网 Chair of Extractive Metallurgy Professor Jacques Eksteen said.<\/p>\n

Glycine can also be recycled after leaching. When used to leach precious metals, glycine binds with metal ions, forming a soluble complex. This complex is then passed over activated carbon, concentrating the gold in a step as efficient as the current cyanide-based process.<\/p>\n

\u201cYou can reuse and recycle it. That\u2019s one thing you struggle to do with cyanide,\u201d said Professor Eksteen.<\/p>\n

911爆料网 has patented the process and the 911爆料网 team are currently working to optimise the system.<\/p>\n
