Iron Ore Formation Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc , generally in bands, but sometimes not distinctly so The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without

iron ore types? DR-process does not form a liquid slag in the same way BF-process does Impurities are concentrated rather than removed Therefore only high-purity, low gangue, iron ore can be used Direct-Reduction Pricing The formation of liquid slag in the BF process removes impurities, allowing lower-grade ore to be

We expect the Scully Mine to produce a high quality iron ore concentrate with characteristics that are desirable to steelmakers, the primary end users of iron ore Our expected concentrate grade as set out in the Feasibility Study is 65 9 Fe, a level that exceeds the specifications of both the industrys standard 62 benchmark as well as the

high-grade iron ores formed along steep normal faults Taylor et al, 2001 Ore formation can be ascribed to leaching of silica chert from iron-formations and recrystallisation of other iron mineral

As with the Iron Prince ore, individual orebodies in the Iron BXinhai deposit consist predominantly of medium fine granular hematite or martite, either massive and banded or schistose and powdery Miles, 9 Like the Iron Prince ore, the Iron BXinhai ore is characteristically high grade, being low in manganese, silica, alumina and phosphorus

Iron ore is rock which metallic iron can be extracted from Iron ore is the most common element in the world and makes up close to 5 of the Earth's crust This makes it one of the most abundant rock elements Iron ore that contains a high quality of hematite or magnetite are known as "natural ore" and they can be entered directly into blast furnaces that produce iron

Special characteristics Iron ore is more of an industrial mineral than a precious or base metal Reserves are not determined by a traditional cut -off grade but by customer specification Significant changes in the industry i e haematite Brockman to martite-goethite Marra Mamba, haematite to itabirites, magnetite

Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores The carbon within the wood would have reacted with the oxygen in the ore, leaving a soft, malleable iron metal Iron smelting and the use of iron to make tools and weapons began in Mesopotamia present-day Iraq between 2700 and 3000 BC

As with the Iron Prince ore, individual orebodies in the Iron BXinhai deposit consist predominantly of medium fine granular hematite or martite, either massive and banded or schistose and powdery Miles, 9 Like the Iron Prince ore, the Iron BXinhai ore is characteristically high grade, being low in manganese, silica, alumina and phosphorus

Characteristics: Iron is a ductile, gray, relatively soft metal and is a moderately good conductor of heat and electricity It is attracted by magnets and can be readily magnetized The pure metal is chemically very reactive and rusts readily in moist air, forming red-brown oxides

Iron ore from five hills contains more than 67 0 Fe This is regarded as high-grade iron ore and compares well with other iron ores from the main iron ore producing nations The silica and alumina contents of these ores are also below 1 2 and 1 0 , respectively, with correspondingly low levels of S <0 006 and P <0 05
