Copper slag

Copper slag

Copper slag is an abrasive blasting grit made of granulated slag from metal smelting processes (also called iron silicate).

Copper slag abrasive is suitable for blast cleaning of steel and stone/concrete surfaces, removal of mill scale, rust, old paint, dirt etc. Suitable for SA-3, SA-2½ and SA-2.

Copper slag blasting edia/grit - is manufactured of the granulated slag of copper refineries, and used for blast-cleaning of metal surface. In different industries it is called different names - abrasive powder, grit, copper slag grit, mineral grit, grinding grains, etc. - but its main use is still for surface blast-cleaning. Internationally the described media is manufactured in compliance with ISO 11126-3[1]

Blasting the grit at the surface is the most advanced approach for metal surface cleaning before paint spraying. The blasting media manufactured from copper slag brings less harm to people and environment then sand. The product meets the most rigid health and ecological standards.

Copper slag can also be used as a building material, formed into blocks. Such use was common in areas where smelting was done, including St Helens and Cornwall[2]
