ABSTRACT Six slags from Volubilis archaeological site roman period (II-III centuries AC) and Jabal Awam ancient mine have been examined for their mineral and chemical compositions by a multi-technique approach (Optical and metallographical microscopies, XRD, ICP-AES and XRF). Mineralogical analyses have emphasised the occurrence of iron oxi-hydroxide, quartz, pyroxene and calcite). The bulk chemical compositions of slags are similar and related to a refining of a homogeneous ore. The very low contents of metals plead for well mastered pyrometallurgical methods. The metal composition of the treated ore is close to a polymetallic ore deposit probably similar to that of Awam mine (Lead and Silver). GRAPHICAL ABSTRACT

Volubilis考古遗址和Awam古矿（摩洛哥）的古矿渣的矿物学和化学组成

摘要已经通过多种技术方法（光学和金相显微镜，XRD，ICP-AES和XRF）检查了来自Volubilis考古遗址罗马时期（II-III世纪AC）和Jabal Awam古矿的六种矿渣的矿物和化学成分。 。矿物学分析强调了羟基氧化铁，石英，辉石和方解石的存在。炉渣的大部分化学成分相似，并且与均质矿石的精炼有关。极低的金属含量有助于人们很好地掌握火法。处理后的矿石的金属成分接近于多金属矿床，可能类似于阿瓦姆矿床（铅和银）。图形概要
