History

(Latin cuprum , from the island of Cyprus) It is believed that copper has beenmined for 5,000 years.


Sources

Copper occasionally occurs native, and is found in many minerals such as cuprite,malachite, azurite, chalcopyrite, and bornite.

Large copper ore deposits are found in the U.S., Chile, Zambia, Zaire, Peru, andCanada. The most important copper ores are the sulfides, the oxides, and carbonates. Fromthese, copper is obtained by smelting, leaching, and by electrolysis.

Science Quote

'You cannot hope to build a better world without improving the individuals. To that end each of us must work for his own improvement, and at the same time share a general responsibility for all humanity, our particular duty being to aid those to whom we think we can be most useful.'
