Reusing the co-products of the steel industry, BlueScope Steel. The worldwide average recovery rate for slag varies from over 80% for steelmaking slag to nearly for ironmaking slag.

Initial characterization of the lead blast furnace slag received from Herculaneum was through a) wet chemical analysis b) scanning electron microscopy and c) particle size analysis. The chemical analysis was performed by dissolution of the slag in aqua regia followed by elemental assay by atomic absorption for lead, zinc and iron.

ladle, or tundish). It is advantageous to separate this iron from the slag for the purpose of using the iron recovered as a substitute for scrap iron and/or making effective use of the slag for applications where iron would be an impurity. Therefore, after cooling, the steel slag is crushed and the iron is recovered by magnetic separation. In

Vol. 2, No. 1 Quantitative Determination of Metallic Iron Content 69 The time for complete oxidation of Fe2+ is a matter of minutes in an aerated solution when pH is above 7.0. The rate of oxidation of Fe2+ by O2 in water is given by Singer and Stumm[7].

In modern blast furnaces around 0.25-0.30 tons of liquid slag with a temperature of approximately 1450°C are produced per ton of pig iron. A number of slag heat recovery systems have been proposed. However none have yet been applied commercially due to technical difficulties that arise in the development of a safe, reliable and energy-efficient system.
