copper smelting production process

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

Continuous Copper Converting - Smelting | Home

This two stage smelting and converting process is being considered for installation at a number of copper smelter sites. The process is very easy to operate and is autogenous with combustion air enriched to approximately 30% oxygen. Solid feed combined with the high level of oxygen enrichment produces a low volume of offgas, rich in SO2.
