Iron ore Facts for Kids Iron ores are rocks and minerals from which metallic iron can be economically extracted The ores are usually rich in iron oxides and vary in colour from dark grey bright yellow or deep purple to rusty red The iron itself is usually found in the form of magnetite hematite goethite limonite or siderite Ores containing very high quantities of hematite or magnetite

Magnetite may form a yellowbrown rust coating if washed or kept in a moist area If a specimen is washed it should be dried to prevent rusting Rust can easily be removed by soaking the Magnetite in a rustremoving solvent such as Iron Out The mineral Hematite is known to form pseudomorphs over Magnetite

Oct 29 2006 · Magnetite and hematite are both iron oxide but with slightly different formulas magnetite is Fe3O4 while hematite is Fe2O3 The only other mineral that is noticeably magnetic is pyrite Our magnetic hematite beads are polarized on on their sides this makes them handy for clasping multiple strands together holding matching bracelets and

Hematite is the world’s most important ore of iron Although magnetite contains a higher percentage of iron and is easier to process hematite is the leading ore because it is more abundant and present in deposits in many parts of the world Hematite is mined in some of the largest mines in the world

Our primary Femineral is magnetite found within a body of host rocks that include volcanogenic felsic rocks and andesites termed so for their composition rather than their origin Hematite is found in small quantities particularly at the surface
