Explore the role of iron silicate in copper slag processing and its impact on efficiency, sustainability, and material recovery.

 

Iron silicate is a byproduct of the pyrometallurgical process of making copper. Known as “final slag,” it emerges when copper is refined or recycled in furnaces such as electric, shaft, or fuming furnaces. Alternatively, it can also be produced through flotation. In Europe, approximately two tonnes of iron silicate are generated for every tonne of copper produced.
