reducibility of magnetite iron ore

The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe 3 O 4) Magnetite ore requires complex processing to separate magnetite minerals from other minerals in the ore to produce an almost pure magnetite concentrate with an iron content of between 68% Fe and 70% Fe that is highly sought after by steel makers...

Iron Ore: Sedimentary Rock

What is Iron Ore? Earth's most important iron ore deposits are found in sedimentary rocks They formed from chemical reactions that combined iron and oxygen in marine and fresh waters The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4) These iron ores have been mined to produce ....

Different Types of Iron Ore

Iron Ore Formation Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc, generally in bands, but sometimes not distinctly so The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without ....

Magnetite forming in iron pipes

Magnetite, with chemical formula: Fe3O4, is an iron ore found in igneous, metamorphic rocks It belongs in the same group of iron ore as the hematite or the maghemite Magnetite is a chemical compound of iron and oxygen and therefore an oxide Magnitite is physically rather stable, as it is a octahedral crystal...

Why is magnetite magnetic, but hematite isn't?
