The main nonferrous slags produced worldwide are derived from the extraction of lead, zinc, nickel, copper, manganese, and phosphorus. 50 Fig. 7.7 illustrates the general process leading to nonferrous slag generation. In most cases, these slags are classified as toxic wastes as they can contain high concentrations of heavy metals, which limits

Cementitious Properties of Nonferrous Slags from Canadian

This report presents data on the characterization of nine Canadian nonferrous slags. The characterization includes the determination of grinding energy, fineness, chemical composition, estimates of glass content, pozzolanic activity, and strength development. Grinding the slags to 4000 cm 2 /g seems to be economically feasible. The chemical

AB In our previous paper, a slag modifiion process involving the mixing of stainless steelmaking and nonferrous smelting slags was proposed for preventing the disintegration of the stainless steelmaking slag. In order to use this method, the behavior of heavy metals especially PbO contained in the nonferrous slag has to be assessed.

Slag Utilization in Pavement Construction

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 appliions.
