Jan 31, 2018· If a mineral deposit is composed of a metal that can be extracted using existing technological methods, then it is called an ore. Magnetite and hematite are two forms of iron ores from which iron can be extracted. Magnetite contains iron in the form of Fe 3 O 4. Hematite contains iron in the form of Fe 2 O 3.
Hematite is economically the most important iron ore, since it is more abundant than magnetite. Hematite typically occurs as one of two varieties; a massive red earthy form or a black specular variety that has a strong metallic luster. The latter variety may be mistaken for magnetite, but is not magnetic.

The chemical composition of many fine iron ore products continues to decline with time as highergrade reserves are replaced with lowergrade reserves for both directship and beneficiated products. It is expected that this trend of declining iron ore product grades is most likely to continue well into the future.
Hematite ore was considered as a potential highdensity rockfill material for the constuction of a major coastal protection work in The Netherlands (the Storm Surge Barrier in the Eastern Scheldt). Three groups of hematite ore from the Itabira District, Brazil, were investigated for their chemical and mechanical stability in a prefeasibility ...

Ryen Caenn, ... George R., in Composition and Properties of Drilling and Completion Fluids (Seventh Edition), 2017. Iron Oxides—Fe 2 O 3. Hematite /Itabirite—Research and actual field use has shown hematite to be an excellent alternative to barite. Hematite is an ore composed chiefly of a soft micaceous hematite and small amounts of quartz.
Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Ironore mining methods vary by the type of ore being mined.
Hematite, heavy and relatively hard oxide mineral, ferric oxide, that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for ''blood,'' in allusion to its red color. Learn more about hematite in this article.
The following is an introduction to these four types of iron ore, magnetite, hematite, limonite and siderite. Iron ore property. Iron is widely distributed in nature (the crust), but since iron is easily combined with other elements to form various iron minerals (compounds), there is little natural pure iron .
