Steel slag can normally be obtained from slag processors who collect the slag from steelmaking facilities. Slag processors may handle a variety of materials such as steel slag, ladle slag, pit slag, and used refractory material to recover steel metallics.
The copper slag has been used for cement material, sand blasting, reclamation and so on. However, most of the copper slag is stacked high as waste since the production exceeds demand. This study on the application of copper slag as fine aggregate for concrete has been started with the expectation of large amounts of consumption.
to refine them, and also arsenic. It may be possible to use the slag as a construction material or for sandblasting, but such uses of copper slag have, historically, resulted in arsenic and lead contamination.

Jul 19, 2018· Impact Assessment Studies on Utilization of Copper Slag as Reclamation Material for Berthing Facility on Marine Flora and Fauna. Concluded that usage of copper slag would not alter the water quality and biological productivity of coastal water significantly and therefore can be utilized for marine application such as berthing facility.
Figure 7 clearly illustrates that the used copper slag has a rather low ANC in comparison with the clay. Sand has practically negligible ANC. The low ANC value indicates that the spent copper slag is not resistant to acid attack. The concentration of Pb, Cd, Cr, Ba, As, Ag, Se, Cu, Zn, Ni and Hg in the used copper slag leachate are fairly low.
