What is smelting? definition and meaning ...

smelting: Metal extraction process in which an ore (usually mixed with purifying and/or heat generating substances such as limestone and coke) is heated at high temperature in an enclosed furnace. After a reducing reaction (see reduction), lighter ore-components (impurities called slag or tailing) rise to the top and float on the molten metal. ...

Lead smelting - Wikipedia

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. One of the reactions to remove iron impurities is shown below:
