Where is Copper Found?
Copper occasionally occurs natively, 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, and Canada. The most important copper ores are the sulfides, the oxides, and carbonates. From these, copper is obtained by smelting, leaching, and by electrolysis.
What is Copper Used For?
The electrical industry is one of the greatest users of copper. Iron’s alloys — brass and bronze — are very important: all American coins are copper alloys and gun metals also contain copper.
Copper has wide use as an agricultural poison and as an algaecide in water purification. Copper compounds, such as Fehling’s solution, are widely used in analytical chemistry tests for sugar.
