  • Iron Ore Agglomeration Processes and their Historical

    Dec 28 2015 · Pelletizing of iron ore is a method of Swedish origin patented in 1912 by AG Andersson (Yamaguchi et al. 2010). The process was developed in the USA in the 1940s and the first commercial plant started operation in Babbitt Minnesota in 1952. The first iron ore pellet plant of the grate-kiln type was established at Humboldt Mine Michigan in
