Bilder von copper oxide refinery
In refining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than has copper. In these operations some of the copper is oxidized to cuprous oxide and dissolved by the metal bath. When the quantity of dissolved cuprous oxide has reached about 6 per cent, the metal is said to have been brought to ...

26.09.2019 · Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper. The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors.
Copper Refining: From Ore to Market | INN
28.05.2019 · In fire refining, air and natural gas are blown through the copper to remove any remaining sulfur and oxygen, leaving refined copper behind to be processed into copper cathode.
Electrorefining of Copper
Fire-refined copper is adequate for noncritical applications such as water tubing, bar stock, or ingots for alloying. Copper intended for electrical uses, however, is produced by electrorefining or sometimes electrowinning techniques. Electrorefining process Virtually all copper produced from ore receives an electrolytic treatment at some stage
Metal rectifier - Wikipedia
Metal rectifiers consist of washer-like discs of different metals, either copper (with an oxide layer to provide the rectification) or steel or aluminium, plated with selenium.The discs are often separated by spacer sleeves to provide cooling. Mode of operation. The principle of operation of a metal rectifier is related to modern semiconductor rectifiers (Schottky diodes and p–n diodes), but ...
