Copper slag is a by-product produced during the smelting of copper, which is then processed into abrasive products. Typically it is composed of Ferro silicate material and oxides formed when the molten slag is quenched in cold water. This cooling process fractures the slag into coarse, angular particles making it an ideal choice in many applications. It is a low-cost expendable abrasive suited for open blast cleaning and due to its low silica content, it does not pose the health hazards created by silica sand. Its sharp, hard particles can provide a fast cleaning action and an excellent surface profile. Applications of Copper Slag include abrasive blasting, building materials, landfilling, road construction, abrasive tools, cutting tools, tiles, glass, and roofing granules.
