Metallurgical production generates ferrous waste at every stage of the process. Solid wastes that arise in metallurgical plants include, for example, blast furnace slag, sludge, dust, scale and others. The composition of these materials varies depending on the source of production. The use there fine-grained iron-bearing wastes is possible within a metallurgical cycle. Attention was paid to the possibility of scaling and subsequent use for the blast furnaces. The scales contain mainly FeO, so energy savings occur in the reduction process. The scales do not contain too much SiO2, which reduces the cost of limestone consumption in the blast furnace. Dynamic granulator was used to package the scales into granules. The granulator allows both homogenization of mixtures of different compositions and pellet-like granules. Bentonite was used as a binder. Subsequently, the produced granules were tested, especially the strength characteristics were monitored. Some substances are considered harmful, as they interfere the run of the blast furnace process, for instance zinc, lead, alkaline compounds, chlorine etc.
