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 ...

A Detailed Look at Iron Ore Agglomeration

Pellets around 4-10 mesh provide a happy medium between iron ore fines (crushed/ground iron ore) and a chunk of iron (mined) for use in a blast furnace. Pelletization offers an effective solution to the items noted above. The ‘recipe’ for successful pelletization, however, is determined through testing. Iron Ore Agglomeration Tests

Iron ore (fines) - Cargo Handbook - the world's largest ...

Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O)) or siderite (FeCO 3).
