Magnetite ore may require more treatment than hematite ore, but end products made from magnetite ore are typically of higher quality than those made from hematite ore. That's because magnetite ore has fewer impurities than hematite ore; in this way, the elevated cost of processing it can be balanced out. Magnetite ore is currently mined in ...

Uses of Hematite (Iron Ore) Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.
