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, 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. The electrical industry is one of the greatest users of copper.
Copper has wide use as an agricultural poison and as an algicide in water purification.
Copper compounds, such as Fehling's solution, are widely used in analytical chemistry tests for sugar. We encourage you to bookmark any pages in this site that you find of value.
