Copper slag is mainly used for surface blast-cleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stream of abrasive grains called grit are propelled toward the workpiece.

Copper slag, which is produced during pyrometallurgical production of copper from copper ores contains materials like iron, alumina, calcium oxide, silica etc. For every tonne of metal production about 2.2 ton of slag is generated.

Air-cooled copper slag has a black color and glassy appearance. As a general rule, the specific gravity will vary with iron content, from a low of 2.8 to as high as 3.8. The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption of the material is typically very low (0.13 %)

Copper slag contains highly toxic elements like arsenic, barium, cadmium, copper, lead and zinc. ... Copper smelter releases copper selenium. They are highly toxic if present overabundant. They contaminate the soil in the vicinity of smelters, destroying the vegetation.Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals.

Abrasive blasting, more commonly known as sandblasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.

Flux is the substance added to to molten metals to bond with impurities that can be readily removed. Slag is the waste material which is removed.
