MINERALOGICAL AND PETROGRAPHIC JUSTIFICATIONFOR THE TECHNOLOGY OF FINAL PROCESSINGOF WASTE STEELMAKING SLAG

Abstract

The steelmaking slag left in the dump after several stages of scrap metal extraction contains small metal particles and other valuable components. They can be isolated and used in metallurgy and construction using the technology of complex separation in a vortex air-mineral flow. With its help, the authors successively obtained binding materials, fillers for concrete and asphalt concrete, iron ore raw materials and metal from the waste steelmaking slag of company ArcelorMittal Kryvyi Rih, PJSC. The technology has significant prospects for industrial use.
