Two typical weakly magnetic iron ores in China, namely East Anshan (EA) hematite ore and Tiekeng (TK) limonite ore, were used in this work. They were obtained from the East Anshan iron mine located in Liaoling province, and the Tiekeng iron mine in Jiangxi province, respectively.
Limonite usually forms from the hydration of hematite and magnetite, from the oxidation and hydration of iron rich sulfide minerals, and chemical weathering of other iron rich minerals such as olivine, pyroxene, amphibole, and biotite. It is often the major iron component in lateritic soils.
>whats the difference between hematite and iron ore
As nouns the difference between hematite and pyrite is that hematite is an iron ore, mainly peroxide of iron, fe 2 o 3 while pyrite is (mineralogy) the common mineral iron disulfide (fes 2), of a pale brassyellow color and brilliant metallic luster, crystallizing in the isometric system. Read More
Limonite is one of the two principal iron ores, the other being hematite, and has been mined for the production of iron since at least 2500 BCE. Limonite was first sought for its uses as a pigment. The yellow form produced yellow ochre for which Cyprus was famous, while the .
>Hematite: A primary ore of iron and a pigment mineral
Uses of Hematite (Iron Ore) 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.
Limonite (/ˈlaɪmənaɪt/) is an iron ore consisting of a mixture of hydrated iron(III) oxidehydroxides in varying composition. The generic formula is frequently written as FeO(OH)·nH2O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely.
Magnetite ore and hematite ore are among the four types of iron ore deposits found in this area. In Minnesota, this type of iron ore is mined mainly in the Mesabi Range, one of the four ranges that make up the Iron Range of Minnesota. In Canada, Labrador is home to the majority of magnetite ore mining.

Jan 25, 2014· Hematite Iron Ore. Obviously as an ore of iron, Hematite is mostly used in the production of iron and then used in the steel industry. There are other uses for the mineral, however, and Ochre is often made up of between 20% and 70% Hematite. Ochre has been used for many thousands of years as a dye and pigment.
Jan 04, 2016· Iron ore is most often found in the form of hematite and magnetite, though goethite, limonite and siderite types are also common. Approximately 98 percent of the iron ore produced in the world is used to make steel.

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). The iron ore, usually, very rich in iron oxides (Fe3O4 and Fe2O3). Iron ores are mostly dark grey to rusty red in color and high specific gravity. Two main types of iron ore used for iron making – Magnetite (Fe3O4) and Hematite (Fe2O3).
