magnetite hematite iron ore - bofafilmclub. 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 industri It is therefore essential for .

Hematite and magnetite are by far the most common types of ore. Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite 48.2 percent, but, since these minerals never occur alone, the metal content of real ores is lower. Deposits with less than 30 percent iron are commercially unattractive, and ...
