Abstract

To efficiently process titanomagnetite deposits in the Urals, new technological solutions must be developed. One such solution is the production of metallized titanomagnetite pellets, followed by electric smelting. Modern electric smelting technologies have strict requirements for the materials used, including a metallization degree above 90%, high metallic iron content (>85%), low FeO content (<1%), and high compression strength. This article explores the potential for producing metallized pellets suitable for further processing into electric arc furnace smelting or for HBI production from enriched concentrates of Gusevogorsky and Pervouralsky deposits under laboratory conditions. The scheme for enriching the poor concentrate of Pervouralskydeposithas been developed. The study analyzed the chemical, phase, and mineralogical compositions of the obtained concentrates. The results showed that the total iron content after beneficiation was more than 65% for both deposits. The study concluded that titanomagnetite iron ore raw materials are suitable for the metallization process. The degree of metallization of burnt pellets, after reduction by gas of CO+N2 composition (90/10%) at exposure (240 min), reached 92% and higher.
