Iron Ore Statistics and Information | Geological Survey

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world''s iron and steel industries.

On What Basis Do Scientists Classify Minerals Realonomics

Since the middle of the 19th century minerals have been classified on the basis of their chemical composition. Under this scheme they are divided into classes according to their dominant anion or anionic group ( halides oxides and sulfides). What is the classification of minerals? The Dana system divides minerals into eight basic classes.
