我国科学家新发现：常见矿石也能“炼出黄金”

Core Insights - Recent breakthroughs by Chinese scientists reveal that common minerals like pyrite can be used to "extract" gold, challenging traditional perceptions of gold sourcing [4][6] - The Earth's gold reserves are estimated to be around 4.8 billion tons, suggesting a potential for significant gold availability if evenly distributed [1] - The majority of gold, approximately 99%, is trapped deep within the Earth's core, over 2000 kilometers underground, making it rare in practical terms [1] Group 1 - Chinese scientists have discovered a process where surface water or underground hydrothermal fluids can oxidize and dissolve gold from ancient geological formations, creating soluble gold complexes [4] - A unique "nano workshop" forms at the interface of pyrite when this special fluid flows over it, which has a strong adsorption capability to capture and aggregate gold atoms into nanoparticles [6] - This discovery opens new avenues for developing more precise and environmentally friendly technologies to extract gold from traditional waste minerals and could guide global searches for new gold deposits [6]
