copper smelting process and methods

The major trend in copper smelting and converting is towards improved capture of the SO 2 that is evolved from oxidizing CuFeS 2 and othercopper sulfide minerals. Improved SO 2 capture benefits the environment and the resulting H 2 SO 4 product can be used …

60 Centuries of Copper: Early Smelting Practice

EarlySmelting Practice. Virtually all the ore used by the ancients was handpicked with only the most worthwhile material being taken. Originally it was probablysmeltedby the Sumerians in shallow pits using charcoal as the fuel. How they first derived the necessary draught to raise the temperature sufficiently to melt the ore is still a matter...

The dry concentrates and fluxes are added to the surface of the molten pool which is strongly stirred by the blast, and then immersed in the melt to complete the oxidation and melting reaction. This is part of copper smelting methods such as the Noranda method, Vanyokov smelting method, Courtney-Entebbe method, and silver-copper smelting method. (b)

Copper Refining: Explained Step-by-Step

Inrefining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizingsmeltingin order to eliminate the common impurities, most of which have a stronger affinity for oxygen than hascopper.In these operations some of thecopperis oxidized to cuprous oxide and dissolved by the metal bath.
