Banded Iron Formations | SpringerLink
The mineralogy of the least metamorphosed BIFs consists of chert, magnetite, hematite, carbonates (siderite and dolomite–ankerite), greenalite, stilpnomelane, and riebeckite (Klein, 2005): the presence of both ferric and ferrous minerals gives BIF an average oxidation state of Fe 2.4+ (Klein and Beukes, 1992).It is generally agreed that none of …

Metal Oxides In Soils: The Effects Of Hematite And Magnetite
Like magnetite, hematite is an oxide of iron and it has the formula Fe 2 O 3. Hematite is not magnetic, and so is not readily removed from soils to which it has been added. It also can occur naturally in soil. Hematite is the most prevalent oxide of iron present in the ground, as such, it is also the largest source of iron for iron/steel ...

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.
