In its pure form or as an alloy copper Cu is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure and there is no critical temperature at which this crystal structure changes. Consequently it is ductile and possesses a high level of electrical and thermal conductivity making it attractive for a wide range of ornamental and practical applications. With cold-working copper becomes harder but it can be made soft again with the heat treating process known as annealing.

The search for copper during this early period led to the discovery and working of deposits of native copper. Sometime after 6000 bce the discovery was made that the metal could be melted in the campfire and cast into the desired shape. Then followed the discovery of the relation of metallic copper to copper-bearing rock and the possibility of reducing ores to the metal by the use of fire and charcoal. This was the dawn of the metallic age and the birth of metallurgy.

Bronze an alloy of copper and tin is both harder and tougher than either it was widely employed to fashion weapons and objects of art. The period of its extensive and characteristic use has been designated the Bronze Age. From Egypt the use of bronze rapidly spread over the Mediterranean area to Crete in 3000 bce to Sicily in 2500 bce to France and other parts of Europe in 2000 bce and to Britain and the Scandinavian area in 1800 bce.

About 3000 bce copper was produced extensively on the island of Cyprus. The copper deposits there were highly prized by the successive masters of the islandEgyptians Assyrians Phoenicians Greeks Persians and Romans. Cyprus was almost the sole source of copper to the Romans who called it aes cyprium ore of Cyprus which was shortened to cyprium and later corrupted to cuprum from which comes the English name copper. The first two letters of the Latin name constitute the chemical symbol Cu.

When copper and bronze were first used in Asia is not known. The epics of the Shujing mention the use of copper in China as early as 2500 bce but nothing is known of the state of the art at that time or of the use of the metal prior to that time. Bronze vessels of great beauty made during the Shang dynasty 17661122 bce have been found indicating an advanced art. The source of the metals however is unknown.

The Copper Age in the Americas probably dawned between 100 and 200 ce. Native copper was mined and used extensively and though some bronze appeared in South America its use developed slowly until after the arrival of Columbus and other European explorers. Both North and South America passed more or less directly from the Copper Age into the Iron Age.

From Ore To Finished Product Copper

As man learned to fashion weapons from iron and steel copper began to assume another role. Being a durable metal and possessed of great beauty it was used extensively for household utensils and water pipes and for marine uses and other purposes that required resistance to corrosion. The unusual ability of this metal to conduct electric current accounts for its greatest use today.

Electrolytic copper refining tanksAnode plates are hung by their handlesin electrolytic copper refining tank. Pure copper cathode sheetssuspended on solid copper bars are inserted into the same tank one sheet between each anode. When an electric current is passed from the anodes through the electrolyte to the cathodes copper from the anodes moves into the solution and is plated onto the starter sheet. Impurities from the anodes settle to the bottom of the tank.

Pure copper cathode sheetsThe refining anodes taken out from the refining furnace is changed into electrolytic copper with purity of 99.99 through an electrolysis process During electrolysis copper II ions leave the impure copper anode and since they are positive migratingto the negative cathode. From time to time the pure copper is scraped off the cathode. Impurities from the copper anode such as gold silver platinum and tin collect at the bottom of the electrolyte solution deposited as anode slime.
