Iron Ore Pellets and Pelletizing Processes

History of use of iron ore pellet in blast furnace The history of pellets began in 1912 when A.G. Andersson, a Swede, invented a pelletizing method. The commercial use of pellets, however, began in the USA after World War 2. Various studies were conducted with the aim of developing the vast reserves of taconite in the area around the Great Lakes.

Iron Ore

Iron ore pellets are spheres of typically 8–18 mm (0.31–0.71 in) to be used as raw material for blast furnaces. They typically contain 67%-72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolostone and olivine is added and Bentonite is used as binder.

Blast Furnace Anatomy #1

Jul 31, 2021First, the iron ore, the raw materials for steel, comes from the Earth. Most iron ores — hematite, magnetite, limonite — contain an average of 60% of iron (Fe). Before the iron ores enter a blast furnace, it undergoes 'sintering' which turns the pristine iron ore into more compact and appropriate sizes.
