中条山与皖南地区古铜矿冶炼产物的比较分析

利用等离子体原子发射光谱法等现代分析测试技术，对采自中条山地区多个古铜矿冶炼遗址的冶炼产物进行了测试分析。结果表明，与同类硫化铜矿床相比，其显著特征为元素Se、Te、Bi、Sb、As、Ag、Hg、Au含量较低，甚至极低，且元素含量比值埘（Se）／w（Te）较高，w（Co）／w（Ni）很高。这些特征应可作为该地区古铜矿7台炼产物区别于皖南地区古铜矿的判别依据。研究发现。中条山炼渣的稀土配分曲线与中条山原生硫化铜矿的稀土配分曲线很相近，但不同于其氧化铜矿；从原生硫化矿→半氧化矿→氧化矿，部分微量元素似乎有一个逐步流失的规律。

Analysis of Ancient Smelting Products from Ore Refinery Sites in Zhongtiaoshan Shanxi Province and Southern Anhui Ancient Copper Area of Province

In this paper,analysis of some smelting products collected from ancient copper ore refinery site in Zhongtiaoshan area by inductively coupled plasma-atomic emission spectrometry is reported.The results indicate that the contents of some trace elements,such as Se,Te,Bi,Sb,As,Ag,Hg,Au,etc.,in the ancient smelting products are lower than those in similar copper sulphide ores with higher content ratios of w(Co)/w(Ni) and w(Se)/w(Te).These characteristics provide a means for distinguishing ancient smelting products of copper ores in Zhongtiaoshan area of Shanxi province from those in Southern Anhui province.Furthermore,the experimental result also indicates that the chondrite curve of rare earth elements in smelting residues is very similar to those in original copper sulphide ores from Zhongtiaoshan area,but different from those in copper oxide ores.A pattern of some trace element contents declining in order of copper sulfide ore,half copper oxidized ore,copper oxidized ore is also shown.
