The recirculation of obsolete scrap in fair quantity may lead to a progressive increase of the level of tramp elements, in particular copper, in steel. But still there are not reliable commercial methods to control the copper content in the metal during steelmaking. A means of treatment by sulfides is promising to creating necessary technology. Some features of molten iron treatment by sulfur and soda were explored in this work. Combined and serial injections of the reagents were examined in the laboratory experiments. After treatment the copper concentration in the iron reduced by 12-45% in different trials at the final sulfur percentage in the span 0.29-0.59%. The final copper content in the melt correlates with the final sulfur percentage. Lower final copper concentrations correspond with more high sulfur percentage.
