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.
