Secondary copper production Unwrought copper is produced with an average copper content of 95 % and is further processed in the anode furnace in a molten form It is refined with additional amounts of copper scrap The melt is initially oxidized with air and oxygen and then deoxidized with natural gas after the slag that has formed has been
Copper is rarely found completely unmixed with other material But it nevertheless sometimes does occur in nearly pure nuggets Like other metals it turns up occasionally in Paleolithic contexts when people tried to work it by stone knapping techniques However it was not worked as a metal until perhaps 6000 5000 BC The earliest use was for

They are amounts designed to cover refining costs For example copper concentrate contracts may define a purchase price based on the LME price at a certain date minus the TC or RC being used at the time London fixing Gold is not traded on the LME Its price is determined for each transaction between market participants The financial institutions in the London Bullion Market Association
Refining Sulfide Ores After smelting the 99% copper rich material is poured into molds as anodes using a casting wheel and transported to the plating house In this form they are ready for the next step which involves dissolving and re plating the copper to increase its purity level Oxide Ores The copper bearing solution from the solvent extraction operations is plated into pure
Finally blister copper is refined by fire refining to produce pure copper In the black copper route secondary copper smelting crude copper is produced during a reduction process and is refined by oxidation in a converter The black copper is an attractive route because it can receive high levels of impurities including Fe Zn Pb and Sn These impurities are removed by oxidation as shown in
