利用波长色散X射线荧光光谱(WD-XRF)、能量色散X射线光谱(EDX)和电子探针分析(EPMA)对南非林波波省Rooiberg出土的史前锡冶炼活动(1650-1850 CE)的玻璃渣进行了分析。这些炉渣被发现含有高浓度的氧化锡，这表明金属回收率较低，导致锡的大量损失。此外，还观察到了骨架锡石、复合尖晶石以及大小从几微米到几十微米的锡屑。这篇文章讨论了锡(II)和(IV)氧化物在熔渣形成过程中的作用，以及冷却过程中析出的尖晶石的晶体化学。
Vitreous slag remains of prehistoric tin smelting activities (1650-1850 CE) excavated at Rooiberg, Limpopo Province, South Africa were analyzed by wavelength-dispersive X-ray fluorescence spectrometry (WD-XRF), energy-dispersive X-ray spectroscopy (EDX), and electron-microprobe analysis (EPMA). The slags were found to contain high concentrations of tin oxide suggesting a low level of metal recovery that resulted in substantial tin losses. In addition, skeletal cassiterite, and complex spinels, as well as tin prills ranging in size from a few to tens of micrometres were observed. The contribution discusses the role tin(II) and (IV) oxides are thought to play during formation of slag as well as the crystal chemistry of spinels precipitated during cooling.
