Based on the abstract of this article it seems that disposal of copper slag is an environmental issue in itself and researchers are investigating ways to incorporate it into building materials eg concrete as a more sustainable means of disposal lshaver m,Proper disposal of copper slag.
Some properties of a typical copper slag are shown in Table I, and it can be observed that air-cooled copper slag has a black colour and glassy appearance. The specific gravity varies with iron content, from 2.8 to 3.8. The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption capacity of the
Aug 15, 2009· Copper slag itself is just the iron silicates (fayalite, ferrosilite) left behind after metals are removed from ores and is considered ecologically benign. If you used it as an abrasive in blast cleaning etc. and there are other chemicals in there -- metals, paint, whatever -- those may be pollutants but treating them depends on their nature.
The benefit of utilizing copper slag in construction industry bestows as substitute to fine aggregates, preserves natural resources and no land management for disposal of copper slag.
Copper slag, or fayalite slag, is a by-product obtained during the matte smelting, converting and refining of copper (Fig. 7.11). 54,59 It has been estimated that for every tonne of copper produced, about 2.2 tonnes of slag is generated, 60 as a consequence of the relatively low grades of copper …
There are many types of abrasive blasting media available. Sand is one of the most common blasting materials. Sand is the least expensive non-reusable media. Alternatives to sand abrasives include other mineral sands with no free silica, metal slag, and coal slag. Coal slag has been used frequently as a blasting material.

JONES* The çotechnical properties of a copper slag are presented.The slag, produced at the Amer¡can Smelt¡ng and Refining Company (ASAROOI plant in El Paso, Texas, is a by-product of refining copper ore in oil-fi¡ed reverberatory fur.
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. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...
CARCINOGEN: Copper slag (CAS No. 67711-92-6) is not listed by IARC, NIOSH or the NTP as a known or suspected carcinogen. However based upon the presence of arsenic and cadmium, the product would be classified as a Category 2
