Copper Smelting Chemistry Tutorial

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.

The Disadvantages of Smelter Sciencing

How copper is madematerial used processing steps

Smelting Once the waste materials have been physically removed from the ore the remaining copper concentrate must undergo several chemical reactions to remove the iron and sulfur. This process is called smelting and traditionally involves two furnaces as described below.

smelting Definition Facts Britannica

Smelting process by which a metal is obtained either as the element or as a simple compound from its ore by heating beyond the melting point ordinarily in the presence of oxidizing agents such as air or reducing agents such as coke.The first metal to be smelted in the ancient Middle East was probably copper (by 5000 bce) followed by tin lead and silver.

12.3 Primary Copper Smelting

A typical pyrometallurgical copper smelting process as illustrated in Figure 12.3-1 includes 4 steps roasting smelting concentrating and fire refining. Ore concentration is roasted to reduce impurities including sulfur antimony arsenic and lead. The roasted product calcine serves as a dried and heated charge for the smelting furnace.
