Copper Slag - an overview ScienceDirect Topics

The granulated copper slag is made up of regularly shaped, angular particles, mostly between 4.75 and 0.075 mm (No. 200 sieve) in size. The air-cooled and granulated copper slag has a number of favorable mechanical properties for aggregate use, including excellent soundness characteristics, good abrasion resistance, and good stability.
