Abstract

The thermodynamic feasibility of reducing agglomerates in iron ore/carbon (ICA) from concentrate mixtures of goethite ore, siderurgical waste and carbon were performed using the HSC Chemistry for Windows V. 6.0 software. Removal by reduction and gasification of Na₂O, K₂O, ZnO and the metallization of iron oxides was performed by using a reducing atmosphere generated by heating the mixtures. Proposed mixtures generate reductions near 100 % of iron with 28 % of carbon and average removal percentages of 85 % of Na, K and Zn have been obtained.
