Ironstone in the world
Banded iron-formations were created when solutions of iron oxides and silica precipitated in alternating layers. The iron oxides form hematite and/or magnetite; the silica forms chert. Iron and silica were supplied by volcanic activity common during the Precambrian period. The deposits accumulated to form distinctive gray (iron oxides) and red b... read more »
IRON ORE CHARACTERIZATION
Iron is an abundant element in the earth’s crust averaging from 2 to 3 percent in sedimentary rocks to 8.5 percent in basalt and gabbro. Because iron is present in many areas, it is of relatively low value and thus a deposit must have a high percentage of metal to be considered ore grade. Typically, a deposit must contain at least 25 perce... read more »
