Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production) Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were treated by .
Copper mining in Arizona, a state of the United States, has been a major industry since the 19th centuryIn 2007 Arizona was the leading copper-producing state in the US, producing 750 thousand metric tons of copper, worth a record $554 billionArizona's copper production was 60% of the total for the United Stat Copper mining also produces gold and silver as byproducts
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% pure copper called cathodes, which will ultimately be made into products for everyday useThe most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different .
The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining
