Sustainable and Comprehensive Utilization of Copper Slag: A

Large amounts of copper slag are produced every year and major fractions of it are currently disposed, not withstanding the multiple ways the material can be used. Application of the slag is often limited by the presence of hazardous elements and their leaching behavior so they can potentially pollute soil, surface water and underground Attempts have also been made by several researchers to prepare copper slag-derived ceramics [22][23][24][25]. However, this recycling method causes a waste of valuable metals since copper slagComprehensive review on metallurgical recycling and cleaning of copper slag
