Taconite pellets are already mixed with some of the other fluxes needed for efficient production in a modern blast furnace. This is designed to be feed into a furnace with metallurgical coke (and possible other fluxes, I am at the other end of the molten process making it solid) and outputs a ~2600F hot metal pig iron with a layer of slag that for steel production has to be desulfurized and ...

Iron Ore Pellet - an overview | ScienceDirect Topics

Raw material for pellets is produced by crushing and grinding low-grade iron ores—typically of the taconite class and finer than 325 mesh (0.044 mm)—and magnetically separating the iron oxide (magnetite, Fe 3 O 4) from the siliceous gangue. The fine particles are reconstituted into moist pellets about 1 cm in diameter, and then indurated by ...

Iron-Formation and Taconite

A much younger iron-formation (only 1.9 billion years old) occurs along the Mesabi Iron Range that extends from Grand Rapids to Babbitt. This iron-formation (above) formed by the same process, but its deposition also involved interplay among sea water, surface rain water, volcanic activity, and some of the world's oldest life forms (cyanobacteria).
