Chemical Composition Data of the Main Stages of Copper
In the El Teniente Converter, for example, the slag is forwarded to the El Teniente Slag Cleaning Furnace Process, which is a batch decoppering process that reduces magnetite and copper contents in the slag. This is achieved through the injection of a solid, liquid or gaseous reductant directly into the equipment.
Copper Slag
The smelting process produces a glass like substance that will settle on the top of the melting copper and is basically the non-copper impurities being separated. The slag is then skimmed off the melted copper and delivered to a "slag heap" or slag dump where it is left to cool. Once cooled the slag is broken up with heavy machinery ...
