Magnetite–hematite ore of the Mikhailovskoye deposit (Russia) was chosen as the object of research. The Mikhailovskoye deposit is located in the Kursk region of Central Russia and has unique reserves of iron ore. The iron ore stratum belongs to the Proterozoic ferruginous–siliceous–shale formation of the lower Karelia (Kursk type).
The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red; magnetite (Fe3O4), which is black; limonite or bog-iron ore (2Fe2O3·3H2O), which is brown; and siderite (FeCO3), which is pale brown. Hematite and magnetite are by far the most common types of ore.
Hematite is the principle ore of iron. Huge quantities are mined throughout the world for industrial production. It is the source for roughly 90 percent of all iron mined in the United States. Hematite was largely used in the past as a red and brown pigment, although nowadays cheaper sources have been substituted.
Iron is the third most common element making up the Earth. Iron is one of the three naturally magnetic elements; the others are cobalt and nickel. Iron is the most magnetic of the three. The principle ores of iron are hematite (70% iron) …
Arrium are the current major producers of iron ore from massive hematite deposits in the South Middleback Range. In 2011 Arrium acquired the iron ore assets of WPG Resources at Hawks Nest including the massive hematite deposits at Buzzard and Tui, and the Peculiar Knob deposit of massive specular hematite.
Iron ore is an aggregate of several iron minerals, the main ones being hematite and magnetite.Iron ore and coal were and remain two key components of the Industrial Revolution, since the modern world depends on …
Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.
Industrial Uses. Hematite is a versatile mineral that finds diverse industrial applications owing to its unique properties. One of the most significant industrial uses of hematite is in producing iron and steel. Hematite is a rich source of iron, and hence is used as a primary ore in iron and steel manufacturing processes.

Powdered bituminous coal of 210 μm size with an ash content of 12.5% and fixed carbon of 54.25% was used as …
This paper mainly highlights the formation of magnetite ore (Fe 3 O 4) by reduction of hematite iron ore (Fe 2 O ). Here, Fe and Fe 3 O 4 are magnetic, while FeO and Fe 2 O 3 are non-magnetic in nature. 2. MATERIALS AND METHODOLOGY EMPLOYED IN THE STUDY 2.1. Materials. A sample of low-grade hematite iron ore was obtained from the Dalli mines in ...
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the ...
