| Abstract | The aim of this paper is the assessment of the total and metallic iron contents from steel mill scale coming from the technological flow of the steel rolling and from the Criseni landfill (Salaj County, Romania). The ten steel mill scale samples were collected from the technological flow of the steel rolling and the ten steel mill scale samples were collected from the Criseni landfill. The determination of the total and metallic iron in the steel mill scale samples was achieved by using a spectrometer based on X-ray fluorescence. There were analyzed ten samples from the technological flow of the steel rolling and ten samples from the landfill. The metallic iron content from the ten samples coming from the technological flow of the steel rolling, varies from 64.4 (sample 8) to 72.7 (sample 7). The metallic iron content from the ten samples coming from the landfill, varies from 58.7 (sample 4) to 63.2 (sample 9). The results obtained show that the steel mill scale is a significant source of the metallic iron. The reuse of the metallic iron content, as a raw materials or auxiliary materials, would contribute to sustainability and circular economy in the iron and steel industry. |
