【人民日报】我国科学家首次在纳米尺度“直播”黄金形成过程

Core Insights - The study reveals a new mechanism for gold precipitation induced by pyrite, challenging traditional views on gold sources and providing insights into the formation of high-grade gold deposits [1] Group 1: Research Findings - The research utilized in-situ liquid phase transmission electron microscopy to capture the dynamic process of gold nanoparticle formation on the surface of pyrite at the nanoscale [1] - Gold nanoparticles are formed not in solution but within a "dense liquid layer" closely adhering to the pyrite surface, acting as an efficient "nano-factory" [1] - This mechanism is effective even in fluids with extremely low gold concentrations, providing a new perspective on gold ore formation [1] Group 2: Implications - The findings challenge the traditional belief that gold primarily originates from deep hydrothermal fluids, offering new insights into the extraordinary enrichment of gold in both hydrothermal gold deposits and surface environments [1] - The research opens new pathways for understanding mineralization processes driven by nanoparticles in nature [1] - From an application standpoint, the new mechanism has significant implications for interface regulation in green gold leaching processes [1]
