- Making Of Copper From Copper Ore
Today most copper is produced from sulfide ores. Copper is an excellent conductor of electricity. Most copper mined today is used to conduct electricity - mostly as wiring. It is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers. Large amounts are also used to make alloys such as brass (copper ...

Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO3.Cu(OH)2. In this experiment, students learn how to produce copper from copper(II) carbonate by heating it to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.

Copper is found in many minerals that occur in deposits large enough to mine. These include: azurite, malachite, chalcocite, chalcopyrite and bornite. Most copper comes from chalcopyrite. The world's leading producer of copper is Chile, followed by the Congo, Peru, China and the US. The majority of copper in the U.S. is produced in Arizona.

Typically, copper ores contain only 4 percent copper, so the vast majority is waste. You can use a variety of different processes to separate the copper from the waste. The exact nature of the refining process depends on which metals and other materials the copper happens to be mixed with and how pure you need the final copper to be. The ...

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

In this experiment, students heat copper(II) oxide in the presence of hydrogen gas to extract copper. The copper(II) oxide reacts with hydrogen and is reduced, producing copper and water. This can be used to show the relative positions of copper and hydrogen in the reactivity series, and can also be used for percentage yield-type calculations.

Instead, the usual ore of aluminum is bauxite - which contains from 50 - 70% of aluminum oxide. Copper is much rarer, but fortunately can be found in high-grade ores (ones containing a high percentage of copper) in particular places. Because copper is a valuable metal, it is also worth extracting it from low-grade ores as well.
