安徽枞阳祖家墩遗址炉渣的科技研究

枞阳地区以其特殊的地理位置、丰富的铜矿资源和众多的古代矿冶遗址，成为探索安徽青铜时代冶金技术发展的重要地区。采用XRD、SEM-EDS等方法对该地区祖家墩遗址出土炉渣进行检测分析和研究。结果表明，祖家墩遗址出土炉渣均为冶炼渣。通过铜硫比和周围矿山开采情况，推测该遗址所使用矿石更可能为硫化铜矿石。根据炉渣中夹杂的金属颗粒判断，祖家墩遗址可能同时存在红铜和砷铜两种冶炼活动，其砷铜不排除是使用氧化矿与含砷硫化矿石共熔还原而成，砷料来源应与铜陵当地多金属矿床有关。

Scientific Analysis of Slag from Zujiadun Site in Zongyang County, Anhui Province

With its special geographical location, rich copper resources and many ancient mining and metallurgical sites, the Zongyang area become an important area for exploring the development of metallurgical technology in the Bronze Age of Anhui province. XRD, SEM-EDS and other methods were used to detect, analyze and study the slag unearthed from Zujiadun site in Zongyang area, Anhui province. The results show that the slags measured are all smelting slag. Based on the copper-sulfur ratio and the mining conditions of the surrounding mines, it is speculated that the ore used in the site is more likely to be copper sulfide ore. According to the metal particles mixed in the slag, it is judged that there may be two smelting activities of copper and arsenic copper at the same time in the Zujiadun site. It is not excluded that the arsenic copper is co-reduced of oxidized ore and arsenic-bearing sulfide ore. The source of arsenic material should be related to local polymetallic deposit in Tongling.
