Magnetite Ore, Magnetite Iron Ore, Iron Ore Mining Process

Magnetite ore often occurs in metamorphic rocks, which formed from ferruginous sediments in both regional and contact metamorphic settings. It is commonly formed by the reduction of hematite and ferric hydroxide minerals in these rocks. Banded Precambrian iron formations commonly contain magnetite ore.
