The need to reduce greenhouse gas emissions and the consumption of fossil fuels leads to the replacement of blast furnace production with direct reduction. The current challenge is to find solutions to improve quality of pellets for direct reduction. In this paper authors describe the results of a study on the effect of bauxite addition on the strength of iron ore pellets produced out of KMA deposit concentrates obtained by reverse cationic flotation for subsequent direct reduction. The relationship between the iron ore pellet basicity and the desulphurization degree has also been examined. The results indicate that it is possible to have control over the strength of pellets out of additionally enriched concentrates by using bauxite and limestone.
