COPPER SLAG

---

Copper slag can be used as a construction material to manufacture bricks, blocks, and other building materials. It is also used as a lightweight aggregate in concrete and as a replacement for river sand.

Copper slag is a popular blasting abrasive due to its high hardness and angular shape. It is used in the cleaning and preparation of metal surfaces, as well as for the removal of rust, paint, and other coatings.

Due to its chemical and mineralogical characteristics, copper slag can be used as partial substitute for silica and hematite in raw mixes to manufacture Cement. The benefits of such a substitution include lower production costs and energy savings. Based on the study conducted by National Council for Cement and Building Materials (“NCCBM”), up to 5% of copper slag in OPC can be utilized.
