The major trend in copper smelting and converting is towards improved capture of the SO2 that is evolved from oxidizing CuFeS 2 and other copper sulfide minerals. Improved SO 2 capture benefits the environment and the resulting H 2 SO 4 product can be used for leaching “oxide” and supergene sulfide minerals. The improved SO 2 capture has

copper concentrating smelting process
Copper Smelting Chemistry Tutorial AUS-e-TUTE. Any copper(I) oxide present will be converted into copper(I) sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example: Cu 2 O + FeS → Cu 2 S + FeO. Impurities form a slag which floats on the surface and is easily removed.

What is produced by copper smelting?
Melting copper ore (compounds of copper and other stuff like oxygen, carbonates, sulfides, ..) produces a molten copper compound. Chalcocite, a copper sulfide (Cu 2 S) or cuprite, a copper oxide (Cu 2 O), for example, melts at 1130 °C ( 2066 °F) or 1232 °C (2250 °F), respectively.

Pure copper metal is mostly produced from these ores by concentration, smelting, and refining. About 80% of the world's copper-from-ore is produced by concentration/smelting/ refining of sulfide ores.
