Answer (1 of 2): Hematite ore is simply mined, crushed, and after that screened into either lump or fines. It is then immediately sold as such. The ore has high iron content, typically between 56% and 64% Fe. Magnetite has higher iron content than hematite. But hematite ore usually contains larg...

Hematite is also commonly used for pigments to create many different types of reds in many applications. Pictographs, or cave paintings, were commonly created many years ago with pigments that hematite could provide. Years later, painters used hematite pigments to help paint some of the beautiful artwork that we can admire today.
