 copper slag is a low cost expendable media suited for impact blast cleaning in open, due to its low cost and silica free nature ensuring no health hazard linked to the use of silica sand. Its sharp, hard cutting edges ensure a fast cleaning action and excellent surface profile preparation. It is one of the most economical abrasives media available for cleaning steel surfaces where recovery and reuse are not practical like in case of shapes during maintenance, tank forms, pipe lines and other large structures. 

copper slag  is typically used for removal of mill scale, rust, paint layers, dirt and old coating; and creation of deep surface profiles or required for superior adhesion of the subsequent coatings. It can also be used as an additive for floor hardening. .
