摘要 大岩子铂-铜矿床的富矿石铂含量高达6600×10-9。我国已有的系列铂族元素地球化学标样中缺乏高品位的铂矿地球化学标准物质。通过对大岩子铂-铜矿床富矿石铂矿物粒度的初步研究,发现矿石中有>5μm的颗粒铂和≤5μm的超微细铂,颗粒铂的粒径介于4 7~11 9μm之间。颗粒铂占矿石样品总铂的0 015%,超微细铂占99 99%,表明该矿石样适合制作高品位铂矿地球化学标准物质。 Pt content in ores at Dayanzi Pt-Cu deposit is 6600×10^(-9). There is lack of high grade platinum-group element geochemical guide sample in China. Preliminary study of Pt-mineral size in rich ores at Dayanzi show that there exist >5μm Pt particles and ≤5μm ultra-fine Pt particles in diameter. The size of Pt minerals is between 4.7 and 11.9μm. Particle Pt occupies 0.015% of total Pt in ores and ultra-fine particle Pt 99.99%. It is concluded that Pt ores in Dayanzi Pt-Cu deposits are suitability to be used as high grade platinum-group element geochemical guide sample.
