In the last years, pelletizing has been playing an important role for iron ore mining and ironmaking. Some factors have contributed to this fact like as: depletion of high-grade iron ore reserves, expansion of Chinese steel production, growth of direct reduction, better performance of pellets in the reduction reactors, and environmental restrictions in sintering. In this scenario, the world pelletizing capacity grew from 350 Mt/year in 2000 to more than 600 Mt/year in 2020. Invented in 1912 by the Swedish A.G. Andersson, the first industrial plant was built in the 1950’s, in USA. Since that time, there were many developments in this field, which improved the performance of pelletizing processes in terms of productivity, energy consumption, product quality, among others. Some aspects of the evolution and growth of pelletizing technology are presented in this paper.
