Ethical issues
The mining industry in the early Middle Ages was mainly focused on the extraction of copper and iron. Other precious metals were also used mainly for gilding or coinage. To begin with, many metals were obtained through openpit mining, and ore was primarily extracted from shallow depths, rather than though the digging of deep mine shafts.
