To process taconite, the ore is ground into a fine powder, the iron is separated from the waste rock by using strong magnets, and then the powdered iron concentrate is combined with bentonite clay and limestone as a flux and rolled into pellets about one centimeter in diameter that are approximately 65% iron.
Before modern mineral analysis, the name "limonite" was given to many of the yellowish to yellowish brown iron oxides produced during the weathering of ironbearing rocks or deposited as bog, lake, and shallow marine sediments. Researchers who studied "limonite" discovered that it is amorphous and has a variable composition.

Limonite Wikipedia. While the first iron ore was likely meteoric iron, and hematite was far easier to smelt, in Africa, where the first evidence of iron metallurgy occurs, limonite is the most prevalent iron smelting, as the ore was heated and the water driven off, more and more of the limonite was converted to hematite.
