Abstract
This article presents the results of laboratory studies on iron‑containing waste generated and accumulated as a result of flotation processing of copper smelting slags at the Almalyk Mining and Metallurgical Complex. In addition to analyzing the elemental, phase, and particle size composition of the material, the study explored the possibility of its solid‑state reduction using carbon. The reduction rate at different temperatures and the required ratio of reductant to slag to achieve complete metallization of the iron contained in the slag were determined. The results of the study suggest that copper smelting slags can be considered a promising source of iron‑containing raw material for the production of metallized iron pellets or briquettes for electric steelmaking plants, especially in regions lacking their own iron ore deposits or where such resources are insufficient.
