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.

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.
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.
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.
A small amount of slag is sold for railroad ballast and for sand blasting grit. A third product of the smelting process is sulphur dioxide, a gas which is collected, purified and made into sulphuric acid for sale or for use in hydrometallurgical leaching operations. Following smelting, the copper matte is .

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).
Copper recovery from the secondary copper slag by the flotation method is an alternate route [12]. The partial enrichment of Sn and Ni is also possible by this method. A flotation scheme used at the Almalyk copper smelter for the processing slags together with CuMo ores was described,

(winter sand) and railway ballast. Most of these markets are mature and are well supplied by alternative low cost materials.
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.
