It is unfortunate that phase studies were not conducted on the Ahar slag. The modern Khetri Copper Plant produces slag which contains phases such as magnetite Fe3O4 and copper ferrites such as CuFeO2, Cu6Fe3O7 and some free copper oxide (Sharma and Shekhawat, 1984). Similar phase studies on the ancient slag would have shown whether (a) such a slag could have been derived from the neighbouring ore containing specific gangue meterials and (b) if so, what temperature and other physico-chemical conditions might have been employed.
