Abstract
A quantitative analytical method for metallic iron was developed for wastes from iron and steel mills. These wastes consist of slags, dusts and sludges, mill scales, spent pickle liquor, and other iron-bearing materials. Accurate determination of metallic iron in these wastes will provide the vital information for the recycling or reuse of these wastes. The new procedure for the determination of metallic iron (Fe0) was developed and various factors that could affect the test result were determined. Pure metallic iron powders were mixed with pure iron oxides with various ratios and then were tested using this method. Testing results had excellent agreement with actual concentration. Samples from several sites have been tested.
