The study considers ways to increase the efficiency of reduction iron oxides from man-made waste (dust electric arc furnaces) using mechanochemical activation (MCA), grinding and pressing. analysis chemical phase compositions dust samples was carried out, which made it possible identify their potential for processing. experiments included a effect pressing at pressures up 300 MPa on materials’ composition, as well an assessment effects coke addition during MCA. To pressure processes, briquettes were fired temperature 1200 °C. results showed that degree metallization increases with in pressure: concentration metallic reaches 19 % MPa, is higher compared 17 initial state without novelty work lies optimizing parameters demonstrating its process. proposed conditions make processing waste, can be used improve environmental economic components production.
