Abstract
The characteristics of OAO ZSMK converter slag are investigated, including a series of experimental melts in a laboratory arc furnace. The losses of iron with converter tailings slag at OAO ZSMK after primary magnetic separation in the slag fields amount to 22.7%, on average (9.0% metallic iron + 13.7% iron oxides). In sorting the slag, the large fractions are enriched with iron oxides—primarily FeO and Fe3O4; Fe2O3 passes to the small fractions. In melting converter slag, some of the iron is recovered, with increase in the content of metallic iron to 11.7%, on average. Most of the metallic iron is concentrated in the large fractions (more than 40 mm), where its content is 18%, on average, as against 5–6% in the smaller fractions.
