Usage of nonferroUs slags Use in the United states In 2000, only 12 states indicated that nonferrous slags were produced in their state. Oregon and Nebraska produced fewer than 100,000 tons per year (Chesner et al. 2000).
Ferrous Materials and Non-Ferrous Metals and Alloys 17 (1) Very good casting characteristics. (2) Low cost (3) High compressive strength (4) Good wear resistance (5) Excellent machinability The main limitation of this metal is brittleness and low tensile strength and thus cannot be used in those components subjected to shocks.
Nonferrous slags have the potential for use as an aggregate in embankments, although there is little documentation of use in this application. (See references 9,10,11,12,13 and 14.) Processing of nonferrous air-cooled slags for use as aggregate involves conventional crushing and screening to meet the specified gradation requirements.
Nonferrous metals do not contain any iron or metals that have an insignificant amount used as an alloy. Nonferrous metals are nonmagnetic. Standard nonferrous metals are aluminum, copper, lead, nickel, tin, and zinc and their alloys.
The dump slag in this study is an old reverberatory furnace slag with a liquidus temperature in the range of 1100 to 1200ºC. On the other hand, the reduced alloy is an iron-rich, low carbon alloy with a liquidus close to 1500ºC. This would imply that, if a slag is at a similar or higher (as is normal for DC plasma arc furnace) operating ...
Steel Slag - Material Description ORIGIN Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling.
The slag is generated during copper concentrates smelting in ratios ranging from 2 to 5 ton per ton of produced copper, and it contains 42–45% of iron. However, copper, sulfur and other detrimental elements affecting iron properties need to be reduced prior to use the slag in steel production.
Industry estimates a volume global market size for non-ferrous slags of 616.7 million tonnes, which is nearly the same size as the traditional ferrous slag market of 650 million tonnes. Changing construction activity and manufacturing orders has impacted on the slag market, this has caused Non-ferrous slag to establish its own supply chains and a range of specific end uses.

Non ferrous slags make up only 12% of the total annual production Described below are the main types and uses of slag commercially available in Ferrous Slag products. Iron Blast Furnace Slag (BFS)
Non-ferrous extractive metallurgy is one of the two branches of extractive metallurgy which pertains to the processes of reducing valuable, non-iron metals from ores or raw material. Metals like zinc, copper, lead, aluminium as well as rare and noble metals are of particular interest in this field, while the more common metal, iron, is considered a major impurity.
An overall review of the current and potential utilization of ferrous, nonferrous, and boiler slags in pavement structures is given. It would appear that the optimum uses for iron blast furnace slag are in cements and base stabilization processes that take advantage of the energy "invested" in the suitably vitrified slag (granulated or pelletized), rather than bulk aggregate applications.
