Sažetak
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.
