Copper
Copper. Copper (Cu) is an extremely useful industrial metal that is ductile (capable of being drawn into wire), malleable (capable of being hammered and molded) and an excellent conductor of electricity (only silver is better). Copper is found in many minerals that occur in deposits large enough to mine. These include: azurite, malachite ...

Copper Statistics and Information | U.S. Geological Survey
Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.

Copper in Antiquity
Copper melts at 1084 degrees Celsius, and so it could be reduced to a molten state of pure copper where it collected at the base of the furnace. Ingots were made by pouring the metal into stone or clay moulds. With more technological developments, notably by the Romans, the more difficult ores of copper sulphide could be exploited.
