About 2 million tons a year are reclaimed by recycling. Today copper is mined as major deposits in Chile, Indonesia, USA, Australia and Canada, which together account for around 80% of the world's copper. The main ore is a yellow copper-iron sulfide called chalcopyrite (CuFeS2). Health effects of copper
Copper ore deposits are known in North America, South America, and Africa. Copper is obtained by smelting, leaching, and electrolysis of the copper sulfides, oxides, and carbonates. Copper is commercially available at a purity of 99.999+ %. Element Classification: Transition Metal.
The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4) and, to a lesser extent, covellite (CuS) and chalcocite (Cu 2 S). These minerals are concentrated from crushed ores to the level of 10–15% copper by froth flotation or bioleaching.
Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-

What is meant by the terms decantation and filtration? Decantation - pour off solvent leaving behind precipitate
Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.
12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg)
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

In 1899 alone, C&H paid dividends to its investors amounting to $10,000,000. In the early 1900's the company employed over 8,000 workers in the Copper Country. The film, Quality Control - From Ore to Finish Product, was produced in the 1940's and shows the copper mining process from deep shaft underground mining of ore to the final, finished ...
About 80% of the world's primary copper comes from ores in which copper is present as a sulfide mineral, for example, chalcopyrite (CuFeS 2) (the most abundant copper ore), bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S). These ores contain typically only about 0.5-2% copper.
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
In mixed ores, nickel, zinc, or lead can accompany the copper; when such ore is mined, these other metals also are refined and sold as by-products.
