Who invented taconite? E. W. Davis of the University of Minnesota Mines Experiment Station is credited with developing the pelletizing process. Since the commercial development of this process in the Lake Superior region in the 1950s, the term taconite has been used globally to refer to iron ores amenable to upgrading by similar processes.

21.06.2018During pelletizing, ore powder is rolled into iron ore green pellets in rotating drums together with water, binding agents and additives. Globules with grain sizes of approx. 15 mm are produced, which are then baked into porous pellets. Pellets are mainly produced by special ore suppliers and then delivered to the ironworks.

Bentonite for iron-ore pelletizing Bentonite for iron-ore pelletizing While interacting with the water, bentonite clay expands and becomes sticky. This property allows to effectively use it as a binder for the production of pellets from iron ore concentrate (wet, crushed iron ore that has been beneficiated).
