The Role of Pug Mills in Processing Copper Concentrates
The smelting process has been the primary means of copper production for generations. The use of a pugmill mixer to mix and condition copper concentrates prior to smelting helps to improve overall efficiency through uniform processing and a reduction in dust, making it an invaluable tool in the copper processing industry.Get Price

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:Get Price
