Ancient Metallurgy - University of California, San Diego

Smelting. Smelting is the basic process by which one produces workable metal from metal ores. The minerals in copper ores are reduced to copper through mixing carbon with the ore and heating the combination to about 1,100°C. (This can be done directly with copper oxide ores. Copper sulphide ores are heated in contact with air first.)

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Copper Ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
