The iron content is high, varying from 40% to 50% in southwest of the deposit through a range of 15–50% in its central part to a range of 50–52% in the western part of the deposit. The average iron ore content is 51%. The mineralization also contains from 0.09% to 1.5% sulfur and from 0.016% to 0.14% phosphate.

Modified date: 08/09/2023. Magnetite is rock mineral and one of the most important iron ore minerals with chemical formula is iron (II,III) oxide, Fe2+Fe3+2O4 .It also as the name magnetic minerals to attracted to a magnet. It is the most magnetic natural occuring minerals in the World. Small grains of magnetite occur in almost all igneous and ...

Properties. In the Earth's crust iron is found mainly as minerals of iron oxide such as hematite, magnetite, goethite and limonite. The minerals that are mostly used as ore for making iron are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4).Iron is quite soft and easily worked, but it has a very high melting point of 1538°C.

June 18, 2013. By. Jeff Desjardins. Magnetite ore, long the leading source of domestic iron supply in North America, Europe and China, is now increasingly relevant across the globe. The perception that magnetite ore is an inferior substitute to hematite ore is now firmly changing. As easily accessibly, economic hematite deposits become rarer ...
