Abstract
The article presents the results of a study of slag from steelmaking arc furnaces, an analysis of the methods of their processing and the return to production of the metal contained in them. In the course of the research, new data were obtained on the structure, composition and properties of dispersed materials currently remaining in landfills after traditional processing of steelmaking slags by crushing and magnetization, and the most rational ways to extract residual iron from these materials and return it to production were determined. For the recycling of magnetized dispersed slag screening, it is proposed to use rotary tilting melting furnaces, which allow not only efficient, carbon-free melting of finely dispersed scrap, but also the reduction of iron oxides contained in the slag.
