Non magnetic ore of iron

Heating and cooling a non-magnetic iron ore causes it to become magnetic? Ask Question Asked 2 years, 7 months ago. Active 2 years, 7 months ago. Viewed 86 times 3 $\begingroup$ I'm a potter. I find what I think are iron concretions in a deep red local clay. I fired these iron concretions to cone 6 (about 2100F) and when I removed it from the

    Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight
