| Abstract: | A new approach for removing copper from solid iron-based scrap is proposed.Copper in scraps is gasified to chloride in air-Cl2 gas mixture at appropriate temperatureby gas-solid reaction according to the principle of chlorinating metallurgy. Thermodynamicanalysis shows that reasonable atmosphere is air-Cl2, PCl2(ini)=0.1-0.2, 850-1 050 K. |
