Hematite | Definition, Uses, & Facts | Britannica
hematite group. hematite, heavy and relatively hard oxide mineral, ferric oxide (Fe 2 O 3 ), that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for "blood," in allusion to its red colour. Many of the various forms of hematite have separate names.

HEMATITE. PROCESSING AND APPLICATIONS
KEYWORDS: hematite, processing, applications 1. Introduction Hematite is an oxide of iron having the composition Fe 2 O 3. Pure hematite, also called "red ore" (in fact, the name hematite comes from the word "hemo" meaning blood), contains 70% Fe [1]. Almost pure hematite occurs on the edge of Cockatoo island in Western Australia.
