Into extractive metallurgy, the large number of the processes of production of pig iron into the blast furnaces has used like iron search, granulated and/or agglomerated material. The sinterization process has designed with the initial purpose the use of ore and fuels with inferior granulometry than 6 mm. These fractions can not be used directly into the blast furnace once they put in risk the permeability of the load, what becomes difficult the passage of the gases, indispensable condition in order to a good performance of this equipment. Into the conventional process, all the raw material from the sinterization has been fed in the form of ore fines to the production of sinter. The researched alternative had been the production of mini-pellets that use in their composition solid residuals from steelmaking and pellet feed, trying the partial replacing of the sinter feed for pellet feed. In order to arrive such goals, steelmaking residuals and pellet feed that were fed into the unit of sinterization from the steelmaking enterprise CST (Companhia Siderúrgica de Tubarão). The methodology of the research has been formulated and tried with the purpose of getting the technical and economical viability from this presented purpose.
