Hematite: A primary ore of iron and a pigment mineral

Aluminum-containing minerals in iron ore are detrimental to blast furnace and sinter plant operations. The two major aluminum-containing minerals in iron ore are Al 2 Si 2 O 5OH 4 and gibbsite AlOH 3. Some progress has been made in using flotation to separate from hematite
