Copper has been one of the most useful metals for over 5000 years. Copper was probably used around 8000 B.C by people living along the Tigris and Euphrates rivers. In 6000 B.C, Egyptians learned how to hammer copper into things they wanted. Around 3500 B.C, People first learned how to melt copper with tin to make bronze.
Copper is leached with sulfuric acid from crushed oxide based ores. The refined copper from this process is classified as SXEW (Solvent Extraction ElectroWon). I visited a copper mine in Arizona where this process was used..
Copper, the first metal that humans discovered other than gold, was highly desirable. But while it was flashy, it was too soft to be ideal for making tools or weapons. Better was mixing in a bit of hard, brittle tin with the copper.

Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO 3.Cu(OH) 2. This experiment involves producing copper from copper(II) carbonate. The copper carbonate is first heated to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.
Copper has been an essential material to man since pre-historic times. In fact, one of the major "ages" or stages of human history is named for a copper alloy, bronze.

Codelco is in first place, and it's followed by Freeport-McMoRan and Glencore. Read on to find out the rest of the top copper-producing companies.
First, in the 1987-91 period, there was a substantial increase in the output of refined copper, as well as a relative decline in the production of blister copper. Second, the state-owned Copper Corporation (Corporación del Cobre—Codelco), the world's largest copper producer, still had an overwhelmingly dominant role (accounting for 60 percent of …
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore).
The copper sulfate solution (the pregnant leach solution) is then stripped of copper via a solvent extraction and electrowinning plant, with the barred (denuded) sulfuric acid recycled back on to the heaps.
PowerPoint - Copper Processing: Find out how copper ore is extracted and turned into copper metal. This is a PowerPoint presentation showing the properties, uses and extraction of copper.
Fact sheet - Copper: Copper is a metal which is mined from the earth and used for a number of different purposes. It was formed as a result of volcanic activity which resulted in large masses of molten rock and hot water cooling and then solidifying into copper compounds. This fact sheet provides information about copper and its extraction.
Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society.
