Copper slag is a by-product obtained during matte smelting and refining of copper. The common management options for copper slag are recycling, recovering of metal, production of value added products such as abrasive tools, roofing granules, cutting tools, abrasive, tiles, glass, road-base construction, railroad ballast, asphalt pavements.
MANAGEMENT OF COPPER PYROMETALLURGICAL SLAGS 543 Introduction During the last years, due to world-wide economic recession and a large inventory of stock, copper reached a historical value of 0.59 US$/pound in 2001. This fact meant closing down many important mining companies in the world, mainly in USA. On the other hand, strong
approval for facilities that provide proper disposal is becoming more difficult to obtain. Copper slag is a by-product obtained during matte smelting and refining of copper. One of the greatest potential applications for reusing copper slag is in cement and concrete production. The use of copper slag in

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.
EPA also proposes two schedules for completing the Mining Waste Report to Congress—one for completing the report on extraction and beneficiation wastes and one for promulgating a reinterpretation for mineral processing waste. October 31, 1983—EPA misses the statutory deadline for submitting its mining waste Report to Congress.
copper slag are produced. The disposal of this waste becomes a concern for environmental protection agencies and governments; thus possible alternatives to the disposal of this material are needed. Some researchers suggested copper slag as a potential suitable candidate for the partial or full replacement of aggregate in concrete.
Copper slag can also be used as a building material, formed into blocks. Copper slag is widely used in the sand blasting industry and it has been used in the manufacture of abrasive tools. In general, the spent copper slag is suitable to be used as a fill material for land reclamation.
What chemicals does copper slag release into the soil or ... 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 (e.g. concrete) as a more sustainable means of disposal.

traces of combined copper in a few slag particles. This copper may, however, be associated with copper-bearing sulfides and/or secondary copper minerals that formed after the slag production. • Sample No. 11-This sample contains noticeable amounts of metallic copper (Fig. 3). In addition, there are secondary copper minerals (probably malachite).
History. Mining waste is one type of special waste When EPA proposed regulations for managing hazardous waste under Subtitle C of Resource Conservation and Recovery Act (RCRA) on December 18, 1978 (43 FR 58946), the agency deferred hazardous waste requirements for six categories of waste—which EPA termed "special wastes"—until further study and assessment could be completed .

Jan 27, 2017· Abstract. Copper slag is a voluminous waste material obtained during the manufacturing of copper (matte smelting process). As its disposal becomes a concern for environmental protection agencies and governments, possible alternative outlets for this waste material are needed.
Copper Slag Its bulk density and angular shape give it an aggressiveness that provides clean, fast-cutting action, considerably increasing production rates. Faster cutting also means that abrasive consumption is reduced, saving you money on disposal costs and clean-up labor.
Proper precautions should be taken to avoid any health hazard. A health hazard may occur if limits for air contaminants exceed PEL limits as per 29 CFR 1910.1000. Proper engineering controls and ventilation should be used to prevent air contaminants from exceeding PEL limits. NIOSH-approved respirators should be used during all
