Copper Production ScienceDirect
The fire-refined copper is cast into anodes that go to the electrolytic cell to be refined to 99.99% pure copper cathodes. Thus, the fire-refining furnace is also called the anode furnace. The removal of sulfur in the fire-refining step is represented by (2.1.14) S in Cu + 2 O in Cu = SO 2 g for which (2.1.15) K ′ = p SO 2 % S % O 2 ≈ 90 at1 天前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 Copper Mining and Processing: Processing Copper

On this schematic flow sheet the major statistics of copper supply and consumption in the United States for 2018 appear.During lead refining,copper is first removed by the addition of sulfur or pyrite at 330–350 °C during a “de-copper” phase. The dross formed (CuS) is then skimmed off the kettle. Copper removal can also be achieved by decreasing the temperature almost to the kettle’s freezing point and drossing of all elements which precipitate atPyrometallurgical Processing of Secondary Lead Material: An

BACKGROUND REPORT SECONDARY COPPER
Casting of alloyed or refined copper products is the final step used by the secondary copper industry in the recovery of copper from scrap material. The molten metal is poured into molds from ladles or small pots serving as surge hoppers and flow regulators. The resulting products include shot, wirebar, anodes, cathodes, ingots, or other cast
