Copper Smelting Chemistry Tutorial - AUS-e-TUTE

2019-6-21  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:

Copper Smelting - an overview ScienceDirect Topics

The leading causes of lead emissions in mining and mineral processing in the United States are lead smelters, primary and secondary copper smelting, and iron and steel foundries. Lead can originate from nearly every smelting and refinery process including: milling, crushing, loading and unloading, sintering gasses, blast furnace gasses, and fumes from molten lead (U.S. Environmental Protection Agency (U.S. EPA), 1995c). Lead
