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.

Zone Refining

Principle of Zone Refining. The principle of zone refining is that the impurities in an ingot or ore of metal are more soluble in the melt state when compared to the corresponding solid state of the impurities. In the zone refining process, the impurities are concentrated at one end of the block of metal so that the rest of the block is purified.
