Ancient metallurgy
At Arisman, some of the oldest evidence of silver production in the world has been found - such as the litharge fragments and cakes. This was taking place around 3600 BC. Arsenical copper production was also taking place.[7]
The ore was mined from some polymetallic ore deposits in the same area. These deposits contain a mixture of copper, arsenic, lead, and silver. First, the ore was smelted, and then the second step of cupellation was used to separate arsenical copper and silver.
