Iron ore deposits of two kinds occur in Texas in two general areas: magnetic iron ores in the central mineral region and brown ores (limonite, goethite, and hematite) in northeastern Texas. Iron is found in considerable quantities in the area of Burnet, Llano, and Gillespie counties ...
A Copper-magnetite iron ore-type deposit was discovered in 1971 by the Geological Survey Department of Sri Lanka in Seruwila in Trincomalee District. This deposit is composed of magnetite, chalcopyrite, pyrrhotite, and pyrite with several other gangue minerals (Herath, 1995). Investigations have revealed that the deposit is …
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 ...
Hematite and magnetite are two types of iron ore with significant industrial applications. Hematite is formed by weathering processes in sedimentary rocks, while magnetite forms during igneous processes. ... The largest iron ore deposit in the world is the Carajas Mine in Brazil, which is home to over 7.2 billion tons of iron ore. ...

In general, the magnetite-apatite ore deposits of the Bafq mining district do contain concentrations of REE within the iron ore and Th within and at the margin of the ore deposits. In Na-Ca metasomatized rocks, associated with Fe-P ore bodies in some iron ore deposits of this district, Th-REE mineralization is reported ( Khoshnoodi et al., …
1. Introduction. Magnetite is a common oxide mineral in igneous, metamorphic, and sedimentary rocks. They also widely occur in a variety of iron ores, including BIF (banded iron formation), Kiruna-type, magmatic Fe Ti oxide, and iron skarn deposits (Dupuis and Beaudoin, 2011, Huberty et al., 2012, Nadoll et al., 2012), as well …
The Pur-Banera belt is one of the largest iron ore deposits, which is part of the Bhilwara Supergroup.

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.
The Y values reflect proportions of the ore's specific generator, i.e. if a deposit uses the sea level generator, then 0.5 is half the world's sea level and 1 is one block above sea level. For example, on a default 256-block high world, an ore with a Y range of 0 - 0.85 using the "anywhere" disc generator can spawn anywhere between 0 - 218 ...

There are two major types of deposit. The first, and by far the most important, is banded iron formations ( BIFs ), so called because they are finely layered alternations of cherty silica and an iron mineral, generally hematite, magnetite, or siderite. BIFs can be divided into two kinds. The first, and quantitatively most important, is found in ...
