Different results can be derived from the experimental copper slag reduction series. The most important factors include the reduction grade of the metallic particles as well as their grain size, the influence of the treatment time, and the chemical composition of the two resulting fractions – the fayalite slag and the copper particles.

Global copper slag (CS) emissions reached 57.2 million tons in 2021. Despite the increasing reuse of CS, the treatment of CS is still dominated by landfill so far, which not only occupies land resources but also causes damage to the environment. The application of CS to cement-based materials (CBMs) is one of the main approaches to …
