  • An Overview of Copper Smelting in Southern Africa

    Throughout the second millennium BC, copper was produced in Cyprus by extracting it from copper sulfide ores. The ancient Cypriots pioneered pyrometallurgical processing of copper, using the surrounding forest to supply energy for the process, and adding fluxing materials from areas close to the mines.
