摘要:
采用X射线荧光光谱、X射线衍射等测试手段,对大冶李德贵冶炼遗址矿冶遗物进行了物理测试、成分分析和物相分析.物理测试结果表明,遗址炼渣的熔融温度高于1280℃;成分分析结果表明,李德贵炼渣中铜含量很低,远低于炼铜渣的铜含量;而其铁含量很高,与欧洲早期铁器时代和罗马时代的块炼铁渣相近;物相分析结果表明,李德贵炼渣的主要物相与炼铜渣没有区别,但炼铜渣中发现一些铜氧化矿和硫化矿.结合对其他冶炼遗物的分析,可以初步判断该冶炼遗址是一处炼铁遗址.工作台面上发现的炼渣与铁矿石的混合物,表明古人很可能已将炼渣回收利用,与铁矿石原料一起回炉冶炼.
Abstract:
Via X-ray fluorescence spectrometry (XRF) and X-ray diffractometry (XRD), smelting relics from Lidegui site were analyzed. The results from physical test show that the melting temperature of the slag from Lidegui site is higher than 1280℃. The results reveal that the copper content in the slag from Lidegui site is far lower than that in the copper slag, but iron content is very high, which is similar to that of blooms in early Iron Age of Europe and Rome Period. The results from the phase analysis indicate that no much difference in mineral phases between Lidigui slag and the copper slag, except some copper oxide minerals and sulphide minerals found in Lidigui slag. Combined with analysis results for other smelting relics, it could be ascertained that Lidigui is a site of smelting iron. And the mixture of slag and iron ores in the site indicates that slag was recycled.
