The beneficiation of the iron ore did not change significantly its base number. The elaboration of ordinary Portland cement using raw mix composed exclusively of rejects from the main exploitation and beneficiation of iron ore is possible with the inclusion of 4.4–6.3% of beneficiation rejects, with a firing temperature of 1400 °C.
