Copper Slags mainly report to the tailings stream from the smelting of a copper concentrate . The slag we used in this investigation was obtained from BCL mine located in the Northern part of Botswana in a mining town called Selebi Phikwe. This slag was classified as a metallurgical waste, hence was disposed by a way of stock – piling …

A widely used and simple method to recover copper from converter slag is to recycle slag into an earlier stage of the copper smelting and refining process [58, …

When copper slag is used as a raw material for clinker production, it can act as both iron adjusting and mineralizing component. Further, it also improves the grindability of the clinker. When it is used as a cement replacement or an aggregate replacement, the cement, mortar and concrete containing different forms of copper slag have good ...

Manufacturing process of copper production produces enormous amount of the copper slag which contains required chemical properties, so it can be used as construction material. This paper contains ...

Porous silicate supported micro-nano zero-valent iron ([email protected]) was prepared from copper slag (CS) through carbothermal reduction technology, and used as a persulfate (PS) activator for removing organic contaminants.Results showed that the properties of the activator were greatly affected by the preparation conditions.

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 ...

This paper aims at the experimental study of durability properties and long-term mechanical properties of self-compacting concrete with fly ash as secondary cementitious material and copper slag as inert material.
