ECONOMIC ENVIRONMENTALLY BENEFICIAL TREATMENT OF SLAGS IN DC ARC FURNACES 363 Introduction A common feature shared by all pyrometallurgical smelting processes is the production of slag. Slag is usually a byproduct of metal production, although there are processes (such as ilmenite smelting, for example) where the slag is the principal product.
Sep 15, 2003· In northern Arizona where the volcanic ash has a redish color, the BNSF uses red lava rock. A former SP line running alongside the San Pedro River toward the Mexican border uses only copper smelter slag, since there was a large smelter in Douglas, Arizona when that line was built and they probably didn''t even have to pay for it.

Copper Slag. Aircooled 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 to as high as (15) The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption of the material is typically very low ( percent).

(winter sand) and railway ballast. Most of these markets are mature and are well supplied by alternative low cost materials.
A primary copper smelter and refinery thus has six subsystems for copper production and about 15 subsystems for internal recycling, waste treatment, and recovery of valuable products. The primary smelter and refinery plant uses concentrate as a raw material, produces copper cathodes, sulphuric acid, and precious metals, and discards slag and ...

As I may have mentioned above, cost is the number one factor. Both the purchase cost of the ballast at the rock quarry and then the cost of shipping it to the destination. Railroad owned quarries (usually operated by a contractor) are cheaper than privately owned quarries so railroad tend to ship the ballast further from railroad owned facilities.
Copper smelting slag is produced from copper pyrometallurgy (both smelting and converting stages), usually grading at %. The slag may also contains lead zinc minerals like galena, sphalerite. Copper mainly dwells in the slag in the form of bornite, chalcocite, chalcopyrite, and metallic copper.

Also, copper slag can be utilized to make the products like cement, fill, ballast, abrasive, aggregate, roofing granules, glass, tiles etc. (Shen and Forsberg, 2003). Copper Slag Processing Recycling today''s copper slag is similarly possible. Recovery of metals from
· If your home has copper plumbing pipes, there is a chance that your drinking water may include a high level of copper. Many lakes and streams are treated with copper to help prevent overgrowth of algae. If you live near a copper smelting plant, there is a good chance your soil has a large amount of copper in it.
rail mounted mud gun and drill on each side of the furnace to assist with opening and closing of the tap holes. The tapped MSEF matte is ladled to PeirceSmith converters and the MSEF slag will be granulated and discarded.

Apr 12, 2005· thanks for the info on the copper smelter slag, i''m planning on having one on my layout so i guess some black balast in the area would be authentic . i''m alos thinking some red ballast would be likely since there''s a lot of red rock up through Sedona, Jerome etc and they must have had to blast a bunch of it to build the roadbed
Copper slag is a byproduct obtained during smelting and refining of copper. The waste copper slag can be used as abrasive tools, road construction, and ballast. Despite increasing rate of reusing copper slag, the huge amount of its annual production is disposed in dumps or stockpiles to date.
RECOVERY OF PIG IRON FROM COPPER SMELTING SLAG BY REDUCTION SMELTING Copper slag is a byproduct obtained during smelting and refining of copper. Copper smelting slag typically contains about 1 wt.% copper and 40 wt.% iron depending upon the initial ore quality and the furnace type. Main components of copper slag are iron oxide and silica.
materials from copper slag. Recovery of copper, molybdenum, precious metals, silica and iron, that is the most abundant component of the slag, are the goals for this research. Metals, commercial compounds, alloys and different forms of iron oxides for steel industry are proposed products.
