    Utilization of copper slag in cement and concrete

    01.08.2008· As shown in Table 1, copper slag has a high Fe content and has been used as an iron adjustment material during the cement clinker production (Huang, 2001). Since the main composition of copper slag is vitreous FeSiO 3, it has low melting point and could reduce the calcination temperature for cement clinker.
