23/01/2005 are no special requirements for the disposal of the material as supplied, the spent abrasive will contain materials derived from the subtrate being

The abrasives media vary widely, from Rice Hulls and Walnut Shells to various Slag, Garnet and Steel Shot. Typical blast cleaning minerals include Olivine, Specula, Hematite and Garnet. Manmade media used for blast cleaning include Plastic, Coated Minerals, Recycled Glass, Steel Shot, Coal Slag, Copper Slag and Nickel Slag.

Abrasive blasting media from coal slag will typically contain nickel and vanadium and a variety of other metals depending on the source of the coal used to make the slag. Copper slag from primary smelters contains significant levels of barium, cobalt, copper, chromium (trivalent), and nickel; whereas copper slag from secondary smelters might contain significant levels of arsenic and lead.

Copper slags are usually considered a waste and characterized only by the final copper content. Large and increasing quantities are being produced and disposed of by stockpiling near the metallurgical plants.

Jul 14, 2008· Best Answer: Copper slag is the waste product of copper ore smelting. It is normally processed to produce usable grit for sandblasting of metal surfaces. It is extensively used in shipbuilding, ship repair, and other steel fabrication industries.
